you should definitely turn the "money spent" notification into a cumulative thing, where the counter adds up instead of creating new notifications, if possible
also would be super cool to simulate a lustcast stream, if you dont want to sit though it
Yes, i was planning to fix this with improvements to the day simulation, there's a lot i can improve.
As for stream simulation, there will be career upgrades, and one of the early ones will let you do that.
Great game. I enjoy it very much and Look forword to the Updates. May you could think about Implementating an ego Vision for both partners. Would be vary nice.
Tanks for your great work
Yes, that's planned. Thank you.
hmm, i wish this game had shemales (futanari) as playable master/as sex interactant for non-master routes. though thats probably not a planned or wanted feature, as per all the roadmaps and update posts i've read so far. could be a neat combination with other characters when it comes to the other non-sissy “paths” such as femboy and co.
You'll have some freedom in Sissy mode, and if you want to turn your character into a dom, you can. In the end, i'll probably combine both modes (once they are both finished) into one, allowing players to create whatever character they want and progress with no restrictions.
how to have sex with other people as a sissy
The ability to have sex with other people, along with all the features mentioned in the roadmap, will be added in the next update (v1.5.0-a3). Thanks.
Hey so I love the game, I'm just confused on how to open a business? Everything is amazing otherwise just I'm struggling with figuring that out.
Also I hate this new Itch.io policy and I am desperately hoping it all resolves properly.
You can't open a business in alpha3, improved and more advanced businesses are coming in v2.0.0-a3. More info is in the roadmap. It's possible to open a business in alpha2, though. Progress->Income->Open Business. Thanks!
Ahhhh okay! Thanks for the heads up there! I love the game and I am really eager to seeing more of it!
Bro this game has potential, I hate Itch's new policy, I recommend moving over to patreon/steam if you can because they won't have the same issue
Hope this survives the NSFW-apocalypse. If not do you have a plan B?
There aren't many options. The game follows all the guidelines, though, so I'm hoping for the best.
really nice game, unique, really nice ui and the amount of content is really nice. i hope you keep on updating this game because its one of a kind
a suggestion. Something that you could add in the game would be JOI, you can do something unique with it too, that i ve never saw any game do, for example, in master mode you could make other sisys to do joi, and if they don t do it right, you punish them.
I really love the game as of now though, can t wait for update 1.5.0. I also really appreciate how you are as a dev, very involved with the community.
Thanks for the suggestion and kind words!
Hey just wanted to ask if you can add FOV adjustment in master mode(I understand that it will be updated in October just wanted to ask you to add it), sometimes I want to see sissy's both face and butt, really appreciate if you can add it in future update
Hi! You got it.
Loving the game so far cant wait for the master mode update
It's me again! Found another bug where the ability to insert or change a buttplug in Master mode sometimes just disappears. The menu is still there, as are the items, and all the animations work as normal, but the button to allow for insertion is just gone from the UI. I tried clicking in its usual location to see if the texture was just invisible but no, it's actually gone. But even when it allows me to insert a buttplug it doesn't show up on the sissy model afterwards. Still having a great time though! I just thought I'd let you know
Thank you!
Game got updated 9 hours ago as of this post... is it anything new or just fixes?
The chastity cage bug in Master mode got fixed, that's about it.
The game is coming along great and I'm reallly happy to see the updated roadmap! While playing, I found an issue while trying to choose a hair style where my sissy seems to have a bald spot lol.
Hairstyles don't use the highest LOD in order to keep things optimized. This will be fixed soon, thanks!
Found a bug in Master mode, where when you put your sissies into a chastity cage, no matter the model, the actual model for the cage floats somewhere between and behind their feet, but their cock still looks like it's in the cage. On the one hand, clearly a bug, on the other hand, it's pretty hot to be able to clearly see how their cocks are progressively forced back into their body as you lock them down tighter and tighter without metal getting in the way. Makes me wish for a toggle to make the cage texture visible or invisible, not to mention other ways to pay more attention to the cocks-turned-clits of your sissies outside of just locking them away. Definitely hope one of the punishments mentioned in the roadmap is going to be the ability to do some c&bt or use a sounding rod.
It was a bug. I'm currently 100% focused on Sissy mode and forgot to test the features that could affect Master mode's functionality. Fixed it. Sorry about that, and thank you for pointing it out!
I'll add the feature to show what the penis looks like inside the cage.
There will be a few punishment options, so I've got you covered! Thanks!
Thank you for the game, I'm having a great time so far! Also, I'm almost embarrassed to ask, but how do I update the game with the latest patches? So far I basically delete the whole file and replace it with the new one but that kind of nukes my progress every time I do it (obviously so lol)
Also! Another bug that's persisted for a while is that shaving is kind of hit or miss if it happens, even if I make the sissy shave his whole body every day on his schedule, but removing facial hair permanently doesn't count towards the feminization goal and soft-locks it for that sissy. Idk if you were already aware of that one, but I figure I ought to mention it
The best way to update the game is through the itch.io app. You shouldn't lose any progress. Even if you delete the entire game from your PC, the save folder should still be there.
Yes, not everything works perfectly yet. Sorry about that! Thank you for the feedback!
as it stands the attraction to men vs woman meter doesn’t make a lot of sense. Like a starting hetero character wouldn’t suddenly want to fuck dudes and then slowly lose attraction to women. An idea may be to add pornography to the laptop(even if just still placeholder images) and have tastes change over time where over time gay is the only thing that increases the arousal meter and straight does nothing.
In Master mode, a sissy gets more attracted to men after having sex. The more they have sex, the more that attraction grows, which makes sense, I think. However, the progression in Master mode is only halfway done, there will be a lot of improvements and tweaks.
As for Sissy mode, the progression system is in development, so the attraction meters don't really do much at the moment.
Thanks for the feedback!
no problem, I do love the game here and you have a solid foundation to go anywhere with.
Another thing for sissy mode that would be cool is if when you add contacts you add a bunch of selectable female contacts that will always have a 100 percent rejection chance.
how do you open a business.
It's in development at the moment. Business is available in alpha2, even though it's outdated. Thanks!
Heyho, maybe i am just stupid but i cannot earn any Tips. I click on the requests and after showing "in Progress" nothing happens. can u help? Thx :-)
Hello. It won't progress on its own, your character must perform the task. For example, if the task you activated is 'Dildo Anal', make sure your character is doing that.
how to make sure?
did you figure out how i cant wthier
Hey, I just wanted to let you know that you are doing an amazing job! Please do take care of yourself while you make this game. I absolutely love playing out my fantasies in this game so it would be sad if you burn yourself out!.
Thank you ussdev.
Hello. Thank you for your kind words!
Haha always welcome! Health is a super important stat lol
Love the new update! I found a bug on it where after editing my character's nails and then backing out of that screen, there was a floating nail on the screen
Thanks! Yep, that happens. I'm aware of that. It will be fixed in the Monday's update.
hey i'm always losing my job idk why
Hello. It's because you revealed your character's face during a live stream. There's a mask to cover your character's face. The game doesn't tell you about this because the entire career/job system is not finished yet, and significant changes are coming in future updates. Sorry about that.
it's ok thank you, and how do i met and chat with poeple ?
Meeting people, having sex, and chatting with them will be implemented in v1.5.0-alpha3, which is currently in development. I'm working on improving all the existing features.
ok and last question sorry, how to cheat and which code exists ? x)
There's only money cheat. Type givememoney while in the Character tab. Works only in Sissy mode.
Hey nice update dev btw any update on the discord ?
Not yet. Knowing myself, I'll be spending a shit ton of time on discord instead of focusing on work. Thanks!
Thanks! I'm aware of these. Master mode's progression is not finished yet, there will be significant changes and improvements.
i had purchased this game before, but for some reason, i can't seem to find the download button. is there any way i could get help with this
If you go to your library does it not show up there?
it does not, no.
You posted about this a while back. Didn't the issue get resolved? I couldn't find your username in the buyer's list, so it's possible you purchased it with a different account. Hit me up on X, we'll sort this out.
it had before, but i guess something might've changed? i had to re-log into everything after replacing my SSD since it had burnt out. i'll see if i can figure it out first.
I know this is vague as hell... but how do I do anything? For example... how the LustLink thing... how do I change settings for it? The last time I played it was also easy to meet people... how do I do that now? Also maybe change the jobs to where we could get weekly paid? Plus, I had to restart my character... nothing was saved from before. And I'm stuck in the masturbation menu... I do apologies if I'm sounding like an ass or am ungrateful... but tutorials are a thing.Forget all that... why do I keep losing my job? Oh, and what happen to my old character?About your old character, you're referring to the early demo, which is not supported anymore.
Contacts, a new progression system, and other cool stuff is coming in v1.5.0-alpha3 (Roadmap). I'll also update the existing demo to the new version once I get both game modes working, which will be after v2.0.0-alpha3. A tutorial will be available once the new progression system is implemented.
I know progress is slow, but I'm doing the best I can, sorry about that.
Your character can get fired from their job if you show their face while streaming.
Edit: typo
Okay thanks, it is a good game... concept. How do I make money as a Master? Then as a sissy how does one meet people?
To make money as a Master I think the only way right now is the dice game and taking money from contacts like that.
When it comes to meeting ppl as a Sissy, its not yet implemented, I think.
I'm really excited for more. This has the bones for an amazing game once there's more content. Especially concerning sissy mode since there isn't really that much gameplay to speak of.
progress seems to sometimes fail to update, i have 0/2 or 3/4 with everything green and full
edit: also sometimes in scenes camera stops responding and i cant use key to refurniture room/dungeon
Progress in master mode is not finished yet and there are ui bugs that display things incorrectly. Master mode will receive a big update after v1.5.0-alpha3. It will fix a lot of existing bugs (including the camera bug you mentioned), add new features and content. Thank you!
hello where is v1.4?
He said sometime this week. Patience :)
Help tab not working
I mentioned that in the release notes. The help tab will be filled with basic info in the upcoming update.
is the ability to open a business back in this update or the next?
The next one after v1.5.0-alpha3 will be a Master mode update. Business is available in alpha2, though.
how to increase luck?
Don't worry about increasing luck in alpha3. Master mode is in the works. If you're into Master mode, stick with alpha2 for now. Thanks.
In master mode how do I have anything other than oral
Change the position
does this game has any audio? or is it just problem with my game
The game doesn't have audio, it's planned for beta.
Hi, I downloaded version 1.3.0 and I would like to have the save from the older version in it. How do I do this so I can transfer the data and not have to play again?
Hi. Alpha2 and alpha3 are two separate builds. They have separate folders, saves, etc. It's better to stick with alpha2 if you're into Master mode, as a lot of features are disabled in alpha3. Master mode will get a big update (business, dungeons, new characters) once I release v1.5.0-alpha3.
I cannot for the love of god find the career tab on master mode. Is it not yet implemented? my character is losing money and I don' really wanna rely on cheat engine any more than absolutely necessary.
Also absolutely love what you are doing with the game.
It's coming in v1.5.0-alpha3, more info is in the Roadmap. Thanks!
Ah! I completely missed that part. My bad. Great content ahead!
2 glitches I have ran into while in Master mode.
1). When sissies wear chastity cages, they either render at their feet, or not at all
2). When setting a shaving task to the sissy in their schedule, they only appear to shave their pubic area, and face. Even when full body shaving is selected.
I'll look into, thanks.
One more issue - the model's heels clip through the stockings.
OK, one more issue that has been present for a while - the lighting makes the skin of the model look like there are color bands. Not sure if this is just a graphical setting or something else. I've attached a screen.
Hey!
Oh, thank you!
Might not be looking in the right place, but i cannot locate where to find the sex machine?
You have to buy it from your room design.
You add it just like you add a laptop. Hover over your streaming area and press 'R'.
Sex machine tips are not working properly. The first one happens automatically, and the rest do not show up in tip menu, and do not complete.
Secondly, are goals not implemented yet? Because I cannot see main goals etc
When a sex machine tip is completed, it will be deleted automatically. So you won't be able to see multiple sex machine tips, only the active one. It's not possible to activate a sex machine tip, it activates automatically.
Regarding progression, all the information is in the Roadmap
Once the first one completes, the rest do not complete automatically.
Also, is there a guide on Master mode? I.e. How to make money, how to open a business etc
I'll find out what's going on and fix it up, it was working. Sorry about that!
Yeah, I'm working on adding guides to the game. Everything will be in the Help tab.
Edit: tips are fixed, you can redownload it.
