Alright nice, this looks pretty interesting. More people making Captivity-like games is great, I have no idea why there are some people even complaining about this CAPTIVITY IS LITERALLY A DEAD PROJECT. if we had one of these for every 10k visual novels released we'd all be fucking laughing.
Also, I love the idea of mod support, even if it's super simple enemy reskins. For these sorts of games where things are made out of bodyparts, that can go a long way. Orcs becoming robots, the haydee robot things becoming normal humans, etc.
Stuff I'd personally love to see for future updates:
-A step away from the Lab area with the next map, including different-themed enemies.
-Male-MC compatible nsfw animations, Female-MC compatible nsfw animations, futanari just using both of 'em.
-Taller or just generally different-sized humanoid enemies. Anything from slightly larger orc-sized people to hulking giants to that 9 foot spooky woman who goes "popopopo". Don't dive into the beasts and monsters front just yet.
Edit: Apparently you can get access to the character sprite files through the game already. That's pretty cool.
