Excellent, but can be tweaked.
It kept me entralled until night 34 when it refused to advance to the next night. Every minute or so the girl and her chaser would appear, though. I also had some trouble switching weapons right after shooting with one. Sometimes the cursor would rapidly switch between the two weapons, but as soon as it was fired, it would fire the pre-switched weapon. Aside from the bugs I think some music would really add some atmosphere to this game. The graphics were what I would expect from a game of this genre. Too much detail leads to much lag; the detail here is perfect.
