So... I'm not sure if I understand the corruption mechanic correctly. It seems like, if you only ever do things that you already have the fetish unlocked for, your corruption will never increase. But if you don't have any fetishes unlocked, the corruption gains can be dramatic in just a couple days. As far as I can tell, this is exactly how it works, but I'm doubting myself because... that's a very weird mechanic. Means you can start loving every single kink and have 0 corruption the entire game, and you can also start pure AF and have max corruption by day 3.
