I think this has genuine potential to be an enjoyable softcore game. Can't believe it never crossed my mind how well exhibitionism could translate into fun stealth gameplay. You've got my support.
Regarding planned features, I understand you intend to improve the AI, which I agree is probably what will make or break this game. If I may make a suggestion, I think what would help make the experience more tense is if some (or all) the NPCs would attempt to follow the player character if they get sufficiently far away after being spotted. Even better if they try to pathfind to their last known location, so you can't just turn a corner or hide behind a fence that is 2 feet from the NPC after being spotted. Obviously, I wouldn't frame this as the NPCs attempting to physically harass the player character, but rather as them being curious and trying to get a better look. I wouldn't make them run after the player either, just walk at their usual pace, so you can get away, but you might mess up and bump into someone else as you make your escape.
On a different note, do you plan to implement sound detection?
Also, I've managed to get myself stuck on the current map's terrain twice over merely 2 hours of gameplay (not really a big deal for an alpha build, but still). Depending on whether you plan to make major changes to the player character's movement options and/or hitbox in the future, these bugs might fix themselves. If not, let me know if you want me to send you the locations after I try to reproduce the bugs so you can stick some small invisible hitbox in there for future releases or something. (EDIT: went to see if I can reproduce it and take a screenshot and in a somewhat funny twist, turns out the PrtSc button gets you unstuck from one of them, I'm assuming it is a unity debug feature or something)
