Quite nice graphics, music and atmosphere. The idea with changing game's name when next test subjects die is quite nice. I don't know if I reached game's end (the room without visible walls) but after reaching last door I just got back to chamber with test subjects. When I tried to play with last subject (10) I found this bug: http://scr.hu/16jc/5ww8u :). Nevertheless nice game :) I really liked bashing at keyboard keys to hack computers:)
