I thought about cool event for cafe girls. As we know main char size while working in cafe is a lot different than real one. So what i propose is some kind of event, where you meet cafe girls outside of cafe and see their real sizes. For example Heather can be pretty petite, while other can be very muscular, so she works in cafe to be more lighter or something like this. Oh well and as someone previously mentioned some kind of detective where girls finds out why their boss is visiting draining grounds from time to time.
Other one. Maybe some kind of way to earn money on draining grounds? Like working as some kind of manager who chooses girls to be drained and draining ones. Maybe some kind of minigame to relate big ones to small ones if its possible.(I hope im not too annoying with suggestions lol)
Also as i notice intellect dont have too much of use, or i missed smth. Great game tho, your all games are good. Also what you use to generate pictures?
