Man... playing this game now when it's so old really showcases both how much these games have changed and how much they haven't. XD Their NTR games really only had minor changes to them up until the Monica game, which is the only one that's drastically different in some ways from the rest of them.
I still prefer their cum collecting games much more than these ones, since these ones are more of a clunky H-scene collector than anything else... but these aren't bad every once in a while... even if the time limit is highly annoying.
Btw, does anyone know if it's even possible to reach ending 1 on the 1st playthrough without Misaki getting any other dicks in her except for her onii-chan's? Some basic napkin math tells me that it's not possible because of certain events and the fact that the higher paying jobs all require under 60 guilt. On top of that, resting only restores 25 stamina in this one, which messes things up even more.
Oh well, not the worst way to waste some time... too bad about the lack of mouse support though. That's always a pain in the ass for me...
