Not much there in terms of gameplay, but the whole design and level of interactivity was cool. I ran it on Mednafen, and it took me a few minutes to realize that numpad 2 and 3 were the B and A buttons, but once I got it, it was very easy to navigate the whole thing (although there didn't seem to be an option to exit the Touch Vivi minigame). It's insanely impressive that you were able to make this via GBA ROM, and the artwork (while extremely erotic and sometimes kinda fucked up) was very well done.
