How is turning dudes into sissies considered to be transgender? They're just femboys
I think this is specifically a sissy-kink based game, so it makes sense it includes elements that pertain to transgenderism
How do you start a business in master mode
Businesses are only available in alpha2 right now. You can download and play it, it's in your Library!
Has the Discord gone up yet?
Not yet. The person who's gonna manage it should set it up and launch it. If I drop 1.3.0-alpha3 (1.2.0 - May 12-18, 1.3.0 - May 19-25) and the Discord isn't ready, I'll launch it myself since I'll have some free time then. Right now I can't focus on anything but the game development. Sorry about that!
Great game! Loving this so far! Can't wait for the next update.
hello dev, is there a possible way to make money cheat? i guess cheat engine is not working
Hello. I'm considering adding the money cheat. I've been asked about this a lot.
You need to search with 'Float' in value type on UE4 games
Open your save file with a text editor and search for the number that matches your money.
Hi, is there a way in master mode to actually have anal sex with the sissy? Even with the sissy fully brainwashed I cannot find an option. Only bj seems to be available.
Or do you have to wait a certain amount of days for it?
Hi. Choose a position where anal sex is available by pressing Tab.
thanks, and is there a way to put them to work?
Yes, but only in Alpha 2 for now. A more advanced business system is being developed for Alpha 3.
Hi I have a quick question in regards to Sissy mode. How is growth calculated in streaming? Is it dependent on how much you interact with the chat, how many tips you fullfill, how long the stream is, how often you stream, etc?
Hi! Since popularity isn't fully implemented yet, this version of streaming is really basic. I'm finishing up the new version, which will include info on how the system works, how to get more viewers (which can potentially be converted to followers, etc.), and the best ways to become and stay popular. I'll release it once it's done, it's a pretty big update, so bear with me please. Thanks!
do you plan to add the ability to jerk off normally, pre chastity? Maybe stream viewers request chastity at some point and pay to keep you locked longer
Yes, multiple ways to achieve orgasm will be added in future updates.
I had a bug with the latest version. For some reason recording videos stopped working and was not actually registering as using energy? If its something I am doing wrong a tip under the side notification to inform me of missing requirements would be helpful :)
Thank you for making this game
You can't store more than 20 videos, you need to post them. A task will be added soon that will automatically record and post a video for you. It does use energy, but there's a small bug that doesn't display this. It will be fixed in the next update. Thanks!
Thank you for the timely reply, I didn't have videos stored unless you mean the published ones? at a certain point I just wasn't able to produce anything new. Thank you again.
I really love the switch to weekly updates that you mentioned in the alpha 3 devlog! This format will allow for the community to get better insight on the features you're working on, provide you with more feedback on those features, and also allow the page to look a lot more active which should hopefully drive sales for you. Overall a good move imo.
It's mainly to release all the main features that I wasn't able to complete in time for Sissy mode. We'll see how it goes after I release them all. I probably won't be able to keep up with the schedule.
Thank you for the update :D
There is currently a bug in the game that causes a second dildo to appear in the studio during the buttplug change to a dildo, hovering there forever
Yeah, I'm aware of that. It'll get fixed when outfit management is added to masturbation mode in one of next week's updates.
Hey dev love the game been waiting for a game like that for year excited to see what's next.
I know you said that the attractive rating was W.I.P but do you have any tip to raise it ? raising the body was easy but I'm not sure what to do raise the face.
At the moment, by only adjusting facial features, and it's tricky because the game doesn't tell you how attractiveness changes while you're making those adjustments. Outfits and accessories don't affect it just yet, but this will be added to the game soon. Thanks for supporting the project!
I dont know if you figured it out already but just by setting all facial features to 50% gave me an 8/10. I have no idea yet on how to get a higher rating.
Heyya! I'm very interested in playing the game, seeing as I've enjoyed the demo, and I would love to experience the new alpha3 update! However, I have no knowledge regarding how itch.io works, and seeing how often the game is being updated I'm worried that by spending my money now I will be forced to buy the product repeatedly. Does buying the alpha now get me access to its future versions, or is it a one-time thing only?
Its will be forever ! Dont worry
I noticed that the models improved with this update! No matter what I did before, the sissies all seemed to have the same general face for the most part. Now, they have more unique faces. Great job!
Thanks! It's still pretty basic. Symmetry breaking will add a bit more variation as well.
Why is this game only with sissys and male mc´s?
Why not adding females and female mc´s ,too? that would be perfect for this game and would sell this game by 1000% more by adressing it to all "tastes".
What do you think about it?
Good question. It's a niche game that aims to do something specific rather than trying to satisfy everyone's tastes. I've mentioned a few times that a female MC will be added to the Master Mode soon. I think it makes a lot of sense to have a mistress as the main character. However, there's no point in having a female sub MC at the moment.
Sales are an important factor because there's no point in developing a game that requires so much time if it doesn't generate income. That being said, I'm trying to create a decent game that does specific things very good, rather than making a game that probably won't ever get finished.
You did a great job! this only was a thought of mine. with only adding females to the game, this game wouldn´t be a niche game anymore. but as i said, only thoughts. i don´t have a clue how much work it is. i couldn´t write the programming of a toaster.
why is the game force me to use
ResolutionSizeX=1920
ResolutionSizeY=1080
even tho i already edit it to match my screen resolution...
i can't play it because it giving me error "input signal out of range"...
can you help me?
Is your monitor's max resolution lower than 1080p? My bad, if that's the case. I didn't test the game on a monitor like that. Sorry about that! I'll fix it.
yes, my monitor can only goes up to 1366x768 on display resolution, above that and the screen just goes black and error pop up...
i hope u fix it cuz i'm interested in playing your game!! :)
I know this has probably already been answered somwhere, but I cant seem to progress past chastity endurance in sissy mode. Is this a bug or something that's coming.
Thanks great game BTW :)
Sorry, progress isn’t ready yet. It’s being tested right now and will be added to the game as soon as it’s ready. It's a little bit different compared to what you see in the demo and the Master mode. Thanks!
Just tried Alpha 3, my first impression regarding master mode is that dev made everything even worse, old save won't work so you should start from the scratch but how do I earn money if I can't start a business? Everything else just as it was before, man I wish dev would at least add some more hairstyles makeups and faces from sissy mode. As for sissy mode, man, it's so empty and buggy at this point, for example I created new profile but set up for a studio was from another profile which crashed the game. No activities, no tutorial nothing, the only sex scene you got is in the studio which laggy as f*ck. I see dev's comment about fix on upcoming Monday, I really hope he'll fix major issues and add some content for a sissy mode so it can be at least playable. On the bright sight: great concept, awesome realisation (just need some polishing) and a lot of potential. Keep it up, ussdev
Thank you for your feedback!
Regarding Master Mode, Alpha 3 creates a new save folder, so your old save files are most likely still there and can be played in the previous version. The priority right now is the Sissy Mode, but businesses are coming back with new features that will improve the experience of running a business, rather than just being a cash cow. Sorry about that.
On Friday, I'll be adding a lot of makeup options, a new hairstyle, and 2 masturbation positions. On Monday, I'll add clothes and accessories. It's still early in development, and my goal is to combine the two modes and make them work together. Of course, there is a lot of bugs.
Could you expand a bit more on the laggy part? Animations are laggy, yes, which is expected since nobody makes polished animations this early in development. I'll look into the studio bug, though, I've never encountered that before. Thanks for pointing it out!
I laid out why I had to push some features and content in the devlog here https://ussdev.itch.io/ultimate-sissy-simulator/devlog/934330/ultimate-sissy-sim... I can assure you, the work won't stop until we get everything running smoothly. Thanks!
By "laggy" I meant that overall objects duplicating for no reason, like double dildo which one in the sissy already and second in her hand. Animations are good in my opinion. I don't know maybe I was waiting for something that can be played but as it is right now it's just "showcase" of what will be , but that's just my opinion afterall it's only alpha. Thank you for explanation I'll look forward to new updates
I already like the new content! Just created a new character and I noticed that when wearing a chastity cage, it clips through the shorts. I know you're working on customization, but it may be something to look out for. I also noticed that when I was customizing my room, my character was just standing outside, through the window
Please wait until Monday, we’ll have actual clothes, these are just for testing things out.
Chastity never clips through shorts on my end, so that’s weird. I’ll look into it, thanks for pointing it out. The character won’t be standing there anymore, it was a test level. Sorry about that.
Hey, just putting it out there if you need any help with game development or testing i can help you. But honestly very disappointed, i have been excited for Alpha 3 update since February, but it gets delayed alway.
Hey. Understandable. I’m doing my best. I decided to release what I currently have working instead of delaying the whole thing for another 2-3 weeks.
i see new version going to test now
I'm guessing there's been a problem.
nvm, it's out, yipeeee
Don't see the download link anywhere =(
is the update out? do I just redownload?
update please come out soon
So excited for the update!
A few more additional tests, just to make sure everything is working.
it's 4am and can't wait :)
Sounds good is it gonna be available before 7
in about 30 minutes, within an hour max. Sorry about that.
i cant seem to buy it...is it because of the update coming?
I disabled it, sorry. Uploading right now, should be up in 5-10 minutes.
waiting update with big hopes
Yes my friend, wait a bit more and you'll be able to cum soon.
Here's my xmas list:
I would like to see the protag be an M2F or CD femdom.
Also, the dice game giving me the win after the NPC scores zero once would be nice.
A lot of people have been asking for a female protagonist, so that's in the works. Eventually you'll also have the option to be a dom in the sissy mode if you choose. The goal is to make the sissy mode flexible, allowing players to find their perfect balance instead of forcing the same challenges on everyone.
I know the dice game is far from perfect, but it's being improved.
Thank you for supporting the project!
Edit: typo
I actually love that the dice game is rigged so I win. It adds a whole layer of helplessness to the sissies. It would be fun to see some dialogue of them complaining when they lose. Like, "I'm not gay". Or "Didn't see that one coming".
Hey guys!
The update will be dropped tomorrow at 6:00pm PT. Please don't have high expectations. While it's a big step forward, it's not a finished game yet. There's still a lot of work to be done, and I'm doing everything I can to make it better, step by step.
Its Alpha 3, I do not expect a finished or even half finished game. I hope I get alpha 1 and 2 combined plus some additional content, thats all. Thank you for all your hard work. 6PM PT is 3AM here in central Europe, its gonna be a looooooong night :D
In Siberia, it will be the 29th
Can't wait for this! Thanks for all the updates. Really looking forward to this next one.
Bra, Your game can be played indefinitly without ever seeing one of those boner busting "this is the end of the content" messages. I would say you are doing great!
Don't be modest ;)
Your game was already really good, and that's why so many people are waiting for the next update.
I just hope you didn't crunch that much.
Anyway, thank you for your work, like really.
I won't lie, I'm waiting for it too lol.
So hyped for alpha 3
3 days left
cant wait
had some sfx issues during the sex scenes (audio not playing for them the dice games sfx works tho) other than that small bug I enjoy the game
That's not a bug. The game doesn't have sound at all. I don't have the complete list of sounds that I need at the moment in order to start working on them, and I didn't want to use any generic placeholder sfx (other than the dice sfx). I mentioned this in a devlog when Alpha 2 was released. Thanks!
thanks for clearing that up im excited for the 28ths update
After buying the game and putting a good amount of hours into I have to say I had a great time and am looking forward to seeing the game develop further! It's not often I see feminazation/sissy content from a maledom perspective which is wonderful, especially with this much potential. I subscribed on patreon, keep up the excellent work and hope your day goes well :D
Hey! Thanks so much for your support :)
Android version?
No, sorry. There will be versions for Mac and Linux upon full release.
Maxed out 2 stories and... oh, I got to tell you, it was perfect. Perfect. Everything, down to the last minute details.
Cant wait for alpha 3
Would be pretty nice to see devlog about next update
Hi. I've bought the game but I'm unable to download it from the link provided by itch.io. Clicking in it doesn't start any download. Is there any other way to download it?
Can you hit me up on X?
Sure. I just wrote you on X
Any news for discord server?
I'll let you guys know when it's ready. It will be up before April 28th, anyway. Thank you for your patience.
Not sure if someone has already said this but there seems to be a glitch where if you permanently remove body hair sometimes the body hair removal progress for sissies doesn't register it probably.
Don't listen to these people that are so unpatient about the next Update.
Dev your game as you did before, take your time. One step at a time.
Your game is pretty good, I love it, keep going. I've played through the 2 stories and maxed them out, at least what could be done in their state.
Don't let other people hurt you. It happened so many times in the past, so many devs abandoned their game because of the success, because of the player base, don't be that person, do what you want to do.
Btw to others, instead of harassing him in the comment section, go do something else, play others (sex) games. Update is coming when it's ready.
Hey! Thanks for the kind words. The game will get much better. I totally understand why some people are feeling impatient. I don’t feel harassed. It’s not their fault. I set a few deadlines because I was pretty confident about the release dates. But since it's still early in development, I keep experimenting with new things, which really messes up my schedule. Then I end up crunching, and that leads to burnout. But that’s on me, it shouldn’t be an excuse for the delays.
I’m on track to finally release it. If I can’t polish some features, I’ll delay those, but I won’t hold up the whole update this time. I get the frustration, people have been waiting for this update forever, and I’m not about to let them down again. Thank you!
