just finished the 0.65 ver, it's kind of grindy since the corruption is all based on how much they drink the drug, and need a certain degree of luck to find the scene you want (especially heather).
as for the corruption level, I hope there's still some higher level on this, considering there's still the under development 'slave' system and all, after all. since if got banged by the MC is already the max level of corruption, just how 'low' the mc is to get such treatment.
and, yeah, I think there's a need to add some more variation on all things here (event, sex option, date location, etc.), since once you get a hang of it, this game will quickly become kind of boring because all you do and all you are practically only that and that again.
well, overall, it's kind of fun, definitely want to play this game again, only, after it's 'completed' already, though.
