Overview

Ultimate Sissy Simulator is a 3DCG adult simulation for players interested in transformation and mind control themes with a dominant, femdom-leaning tone. It plays as a slow, methodical character-driven experience rather than a fast-paced game.

Gameplay

You build a male character and work through a network of contacts, using persuasion and manipulation to get them to agree to increasingly compromising requests. Once a contact accepts, you shift into a training phase, using conditioning and mind control to reinforce the ideas you've planted until they fully embrace their new sissy identity. Progress depends on managing multiple contacts at once, each at a different stage of persuasion or conditioning.

Features

Character creation for your own protagonist before you start building connections
Point-and-click interface with a first-person POV presentation
Layered conditioning system that turns persuasion into long-term behavioral change
Themes of male domination, submission, and identity transformation throughout

Changelog

v2.0.3

Attractiveness should now display correctly, but the final formula isn't active yet. I'm still testing it.
Fixed an issue where setting up an appearance and then switching to the Toys tab would completely reset the appearance settings.
Fixed a bug where toggling the body type during character creation in a new game would offset the hairstyle.
Switching appearance slots no longer hides an equipped plug or chastity cage.
Body modification randomize buttons should now work properly.
Keyholders can no longer be removed from your contacts. This should prevent you from accidentally losing the key.
The Buttplug comm used to plug all your contacts due to a display bug. Fixed.
Chastity could still be equipped even if the corresponding comm failed. Fixed.
The Dress Up comm now has several different presents, each applying a different outfit set with random colors picked from a selection of clothing color presets.
Fixed coffee shop reputation and XP gains. There are still plenty of bugs in the coffee shop, though. I haven't gotten around to fixing those yet.
Anus tightness now changes during masturbation sessions. It gradually decreases during a session and recovers during the daily simulation.
Sissy names should now display correctly.
Fixed the sissy schedule system. Schedule limits should now be applied properly.
The New Game Archetype screen no longer allows you to start with fewer than 3 traits. The whole system is designed around having 3–5 starting traits, with another 3 traits available to unlock later.
Added a new Masturbation task. It's experimental and still pretty buggy, and it doesn't display toy information yet. It lets you record a masturbation session, with the resulting video file being added to your phone. This works similarly to how the Record Porn Video task used to work. That task will be removed once the Masturbation task is finished.
Fixed an issue where a toy would keep floating around if you exited the menu while your character was holding it in the Toys tab.
Added hairstyles for masculine male characters.
Added basic facial hair assets for masculine male characters.
Added a button that removes broken contacts from your contact list. If you see an empty or unknown contact in the list, just hit that button and hope for the best.
Fixed a bunch of other minor bugs here and there, although there's still a ton of them left.
