Some scenes already have moan sounds. Mostly the longer ones though because some loops are quite short, and adding moaning in would just make the same moan sound playing on repeat, which can be quite annoying.
Just finished the game, it's good I should've finished it before commenting haha.
Keep up the good work my friend. I'll support when I have the funds Haha
