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.
Hello, just tested a bit 1.3.0 and got some problems
1) Tips menu not working, basic (not machine) tips just not adding, so can't start streaming.
2) Forced to buying dildo 2nd color every time, it's just not saving.
There are few small bugs with clothes but need more testing.
Hi. Tips have been fixed already, you can redownload it. Post it here if you encounter any other bugs.
The dildo color bug will be fixed in the next update, and there will be a lot more styles and the ability to set a custom color. It requires a little more work, it's not finished yet.
thanks
Has the update been completed? I don't think it's showing up in downloads yet.
In about an hour. Doing final tests to make sure everything works.
Will it be possible to update the game version without losing the current game?
Don't worry about it, you won't lose any data.
Hi there will be a release for macos ? Thank you ! Waiting for new update so much :)
Hi! The beta version will be available for both Mac and Linux. That's the plan. Today's update should be out in about 10-12 hours. Thanks!
Are you not able to make contacts like in the demo version? I can only be a cam model or use lustlink, will male on male stuff be added later?
I think in v1.5.0-alpha3 we’ll have other people in sissy mode. For now it’s still being developed.
Check the Development log. Roadmap Update
will you be adding dice roll mini games to sissy origin? If yes will the odds be stacked against you as opposed to in your favor in master mode
There will be other new mini-games. I don't know if the dice game, in its current state, will make it to Sissy mode.
just bought it but its not completing the purchase but the money has been taken
I won't be able to help you with this, unfortunately. That's not something I have control over. I didn't receive any payments from you, so you will need to contact itch.io's support.
Not sure if you are aware of this though. The chastity cages seem to be misaligned. I know you're working on it. Let me know if you want a photo.
Thank you, i'm aware of it.
Hi everyone, first I'd like to say this game is awesome, thank you for your hard work!!!
I'm pretty new in this game, so I have two questions:
1- In the lustcast how can A2M and Gaping be performed? Im basically put the sissy to masturbate, and then opening the stream2- Is it possible to find other a person in the game?
Thank you!
Hello!
Thanks for supporting the game!
Was the ability to open a business removed from Master Mode? I'm not seeing it...
Temporarily removed, yeah. T’will be re-added in a future update, I’m pretty sure. If you scroll down the comments you’ll see dev say that somewhere.
Also announced this.
It’s linked in a comment ⬇️
[7 comments down (ignoring replies)]
I’m sooo excited for next update… ahh. I cannot sleep. 😂 I have issues.
I’m a completionist. Can’t wait for there to be achievements and rewards and such.
Are we gonna have things like contacts eventually? Eye color stuff? Or completely change face structure / make a new account to undo face being revealed.
Also partly hoping we eventually get a mode where we can be muscular overall- but also need to be thicc.
Kinda wanna be able to edit thighs, shoulders, and back too, but idk. I need to sleep. 😂
Main point is, this game is awesome.
Thanks for your feedback!
Eye color is definitely on the list. Achievements and rewards for both careers are coming in the next update, but they'll be pretty basic. All the progress-related stuff is aimed for v1.5.0-alpha3, which is going to be a big update.
I like the idea of 'unrevealing' your character's face if there have been significant changes. Definitely considering it.
Every part of a character's body is editable, but there are no sliders for it. You can shape your character's body with workouts and maintain it with diets (which are coming in the next update).
purchased the game, is their a how to? I am on windows and I can create the character but that is it. No story or a way to continue? Alpha 3 , maybe use the older version?
There's no story in the game. You play it however you want, that's the point. New progression, as stated in the roadmap, will be added in v1.5.0-alpha3, which will give players a lot more options. Right now, there are just two basic careers.
I cannot do anything i have tried for over 2 hours. Customize character that is it. Nothing else is working. Each tab I can click this or that but that's it. I probably am missing something.
Basically, there's a 'home' button in the Character tab. Click on it, rent a room, and set up a streaming area in your room. Add a laptop to the streaming area and start a webcam career. Your character's stats are pretty weak when you're just starting out, so you might want to use a butt plug for about 20-30 days to increase anal endurance. There's a lot to cover in just one post, but give it a try and let me know if you have any other questions.
I just started the game and i cant figure out how to save my game. I think im missing something but how do i save the game?
Click Exit (bottom left corner), confirm, that's it. It saves it for ya.
Thanks a lot! I was afraid to just exit game lol
I am not getting sound, Is this a known bug. Im not running in VR
There's no sound in the game yet. It's planned for the beta version. Thanks.
Can the game even run in VR ? I see steam vr starting everytime
It does, indeed, open Steam VR. I'll fix that. Thanks for letting me know!
Edit: and no, this is not a VR game.
Are you planning to add fisting?
It's definitely on the list.
love the updates! probably just me but I was hoping the combination of the two modes would mean you could turn your character into a sissy as well as "recruit" your own, don't know if that is planned for the future but i'm hoping for it lol
Yeah, something like that is planned. There will be a few ways to interact with your other created characters from both Master and Sissy modes. Thanks!
I can't get a loan neither can I start a buisness for some reason I just can't find a tab for these things
Here's why, sorry about that.
so currently there is no way to start the business??
Not in alpha3, no.
Great work, I like the way it goes)
1) Are You planning to replace bodies in menu of master mode with new body present in sissy mode?
2) Are You planning to add sound in game in future?
Oh... and Thank You for timely updates, please just don't burn out)
1. Yes, but there will also be an option to use old characters.
2. There's a lot of posts where I've answered this question, here's one. So the answer is yes.
Thank you :)
"This game is intended for mature audiences only and is NOT suitable for individuals under the age of 18 (or the legal age in your jurisdiction).."
Oh my brain just skipped the most important part. Sorry.
Are we not able to start a business anymore? I can't find the option for it anymore.
Master mode is getting a big update after v1.5.0-alpha3. A lot of things, including business, will be improved. It's half-done in alpha3, so it's disabled for now. Alpha2 is available in your library, so you can still download and play it. Sorry about that.
When will you release version 1.2.1?
6:00pm PT
Thanks Dev.
Hello i want to ask that if i buy this game will i able to play all version that coming soon or etc? or I am just buying existing versions only. And also i wanna know if I played old version then downloaded new one my progress will reset again to zero?
Hello. You buy it once, and updates are free, as they should be. The demo version is an old build and won't be getting any updates. The progress for the new Sissy mode will be completely different. The current demo will be replaced with an updated version as soon as it's ready. Thanks!
I purchased the game so waiting for uptade that will come soon. Thanks <3
I don't know if I'm doing something wrong but, I can't access the underwear tab in the sissy mode.
The 1.2.1-alpha3 patch will add underwear options, so you're not doing anything wrong. Sorry for the confusion.
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.
