You can eat, peep, sleep, look at a map full of places you can't go, look at inventory in an online shop you can't buy - even with the money you make blackmailing your smoking ?sister? ?roommate?, gamble one poor online game, bathe, and jack-off. Oh, yeah, and watch TV with ?Mom? ?landlady?. Controls are awful, (half only appear when dialogue box is open,) MC gets auto-shunted to his room way too often.
On the plus side - there are rooms. And characters. The room art is better executed than the characters, though. It never froze or crashed before I got too bored to go on. You don't need to spend a lot of time looking for things or questing or whatever - mostly because you're not given any idea of what you should be looking for or doing or whatever. You can actually spend the entire day in bed jacking-off without interruption! The translation is reasonably understandable.
I might look back in 6 months or so.
