I think the game is nice, but it could use some sounds and audio (maybe some music too, to make the atmosphere more appropriate). For example, in scenes where Tifa is sucking a big dick, some gagging audio or something like that could be added.
I also thought during the game that I would like it more if the animations were better, but I understand that in this case this would be something that would demand more time and animation skills. Anyway, definitely what bothers me most, and that I think the dev should give some attention, is the lack of audio.
