Some info on the new progression system and more
Hello, everybody!
I've been on this since Friday. I thought I would write it up really quick when I got home. Nope, I've been experiencing horrible brain fog and can't concentrate at all. It's getting better, though.
Anyway, I wanted to discuss some changes I've made after a lot of testing. Some things just weren't right, and I had to figure out the best way to implement them.
I only want to focus on progression and some of the features that are part of the new character system in this post.
A heads-up: nothing here is final, there will be a lot of visual updates in the future. For now, it gets the job done, and that's what I need.
This update will be out on November 18, 2025.

Choosing goals at the start of a new game worked, but after some testing, I realized that it wasn't ideal. It limited the player's options significantly. Instead of requiring players to select goals at the beginning, I went with a sandbox approach. Now, everything is available from the start, and it's up to you to decide what you want to complete and when. There are some limitations, of course, but it works much better this way.
I'll talk a little bit about the Sissification goal. There are two options: you can choose either the 'Self Sissification' option or 'By Master or Mistress.' Option one is pretty straightforward, you complete stages that are divided into challenges, similar to the first build of the game.
Option number two is quite different. You have to find someone who will give you tasks and guide you, so you don't really have to worry about progression, you just need to complete the tasks you're given. There's a new app that you can find on your smartphone, it's basically an anonymous kink 'dating' app. It allows you to set up your profile and search for others. Other users can also reach out to you through the app.
After you find the right person, you will start to receive tasks, requests, and messages from them. Obviously, it's up to you whether you choose to complete them or not:
Since the app is anonymous, some users will remain anonymous until you meet them, while others may reveal their identity right away. It's not always straightforward, though. You never know who you might find. There are both good and bad people, which can lead to different scenarios:
- They may give you tasks with no bad intentions at all.
- There's a risk of getting kidnapped.
- They could try to blackmail you.
You could end up in captivity, either voluntarily or as a result of being kidnapped. A lot can happen from there, they might release you at some point, or they might not. You can escape from certain locations, but there are also places where escape is impossible. If you've been kidnapped and your captor hasn't revealed their identity, that's a bad sign. I could go into detail about everything that could happen, but I don't want to spoil it just yet.

You'll receive offers from your captor, and it's up to you whether to accept them. They might put you in a cage and limit your food, water, and hygiene. To regain your basic needs, you'll have to agree to certain deals, otherwise, your character could ultimately die in a filthy basement. There are options, though, you can play mind games and eventually escape, along with some other unexpected twists. Anyway, you'll discover all of this on your own when it's out.
New characters now have preferences for things like sexual interests, their partner's appearance, and physical parameters. A lot of stuff in the game rely on these preferences, things like sex, relationship meter, behavior, sponsorship, and sexual interest. They can keep certain info private, like their health or diseases. If you build a good relationship with them, they might share this info, but they can also lie about their traits or health, it all depends on their unique set of traits:
Each character has their own unique traits that affect how they act and make decisions, adding a lot of variety to their behavior. Right now, there are 19 traits, and I'll probably add more later. It's not perfect yet, but it'll get there eventually:
There's a new Masculinity/Femininity meter that's been added. Your character's pose will change depending on the value, and it also affects how others perceive your character. For example, coworkers might notice some behavior changes, since there's a coming-out mechanic:

Primary sexual stats have been completely revamped, they're now experience-based and unlock new things as you level up. I didn't want to make level-based stats, but after a lot of testing and feedback from the testers, I realized this works best.
Your character can get brainwashed, and certain actions will trigger idea planting. You can't plant ideas yourself, and you don't need to level them up manually (like you do it in the Master mode) they'll complete (or not) automatically based on your actions and activities. There are about 30 unique ideas, and not all them sissification-related.
I finally added penile stimulation, which has been requested a lot. It was definitely time, especially since there are tasks that require it. Now your character can jerk off, use a vibrator, or hump a pillow. There's also a self-facial mechanic too, but I haven't finished the animations for that yet:
I wanted to make a separate post about the new sex system, and I might still do that, but for now, I;ll just point out some key features. Characters now have a 'satisfaction' meter based on their experience, which indicates if they're satisfied oe nor when a sex session wraps up. This is crucial for a prostitution career and can affect relationships, sexual interest, and more.
All the calculations happening under the hood have been redone, so the whole sex system is much more balanced now. It's easier to add additional actions, and it will support multiple partners in the future, though I haven't implemented that yet. It should be relatively simple when I get to it. In the old system, that wasn't possible at all. Plus, live streaming during sex will also be a thing.

Now, I'm 100% sure I forgot something, but I don't know what. Anyway, this is what I've been working on. Sorry for the slow progress, but to create a solid and maintainable project in the future, I had to redo the whole thing. Progression tracking can be tricky, especially with so much going on.
I built a framework that makes it easy to add new goals and scenarios. I've been making everything from scratch since there aren't really any ready-to-use plugins for what I need. And you guys know how logic programming goes, you get stuck, you iterate, rinse and repeat until you get something that works just the way you want it.
Thanks for stopping by! This it not everything I'm working on right now, and I hope you'll enjoy it when it's out. I've done a lot of research on the topic and am trying to implement all the must-have features. I'm always open to suggestions, so feel free to hit me up on X/Twitter, I reply to DMs pretty often.
Make sure to follow this page and me on X so you don't miss the v1.5.0-a3 release. I really appreciate your support, I'm so grateful to have such a wonderful community.
Stay safe out there, love you all!

Update? :^(
6:00pm Pacific Time, it's on the main page.
Edit: 24-48 hours delay. i know i'm crushing you with these delays bro, i'm sorry.
I miscalculated a bit, it won't be the 18th for me anymore XD
is it 6pm, or a few hours later? you said there would be a delay
a few hours delay, but it will be out before midnight. I found a few bugs causing crashes, and now i'm fucking paranoid there might be more. sorry about that.
you said sth about a delay... do you know how much?
6 hours max, sorry about that.
Edit: 48 hours max, i got stuck, here's an explanation. sorry again.
Ah okay, that will be during the night for me. So i will test the update tomorrow
don't stress yourself out too much. sure we're eager for it, but also you need to balance it with yourself. it is normal and completely natural to be stressed about it, but don't let it consume you. be strong man, and be calm.
hey dev ihave a question when the time the update out? i mean like on the clock.
hey. the goal is 6:00pm PT, but there will be a few hours delay like always since i have a huge list of things to test one more time and make sure everything's running relatively smoothly. thanks.
ight thanks for the reply man.
Hope update coming out with no delays
probably a few hours delay
looks lovely, as a sugestion, it would be cool to be able to guide others into sissification too, like threesome and stuff.
Normally not one to spend money on itch games, but this seems very promising!
Jeez bro, you went above and beyond for this update, is definitely worth the wait. Thanks for your hard work!
OMG i cant wait for the next update! You are making this game way better than i thought possible. Thank you for all your hard work
I hope we can opt out of the odds of being kidnapped...
amazing work as always, cant wait to play
It looks amazing! Especially the sanbox and kidnapping, I,ve always preferred forced sissification, it's way more appealing imo.
As for suggestions, I would love to have more visual options, like long foreskin (which look amazing on useless limp clitties), shorter height options (140-150cm) , more cute hairstyles and maybe more interesting boob shapes (hrt boobs then to be small/budding, to not look like a shemale).
Can't wait for the update, the wait was well worth it! ❤️
Woah, upvoting this one.
Damn you cooked, can't wait for the update ussdev. Thanks for the hard work
When will it be released?
November 18
Whoa, I think this is the biggest update yet, it will be worth for wait
Will there be a system of penile stimulation not working if penis is atrophied? Like using 2 fingers or a frustration meter? Also will penile stimulation animations be available for during sex with a partner?
There isn't 2-finger masturbation right now, and penile stimulation during sex is not implemented, but both are pretty easy to add. If the penis is atrophied, pillow humping and vibrators are the only options. There's no frustration meter per se, it's all about arousal, which plays a big role. If a character can't get off, it can lead to some frustration over time.
Your hard work has proved awesome, man. Literally everything that I wanted will be in this update, I can't wait
Holy shit, this sounds awesome
Damn, it all looks fantastic. Can't wait to see the mechanics in action.
thanks!
Love the progress!
Is the female dom/master still on the table?
yes, it's planned for the v2.0.0-a3 update. you can check out what's coming in the upcoming update here.
Nice work so far.
Thanks :)
Despite all the delays, this is truly excellent progress. Although it doesn't even cover half of what's to come, it already looks like a more solid project. Excellent work!
It's sad that I have to wait another month :^(
I really want to try it now
It's not ready yet, there's still a lot of testing and polishing to do. I don't wanna release a buggy update this time, so i need to take my time. Sorry about that. And thanks, i appreciate it.
