Good sound effects, the heavy reliance on trial and error means loads of frustration for the person playing. If it's tough to kill the guy before the alarm goes off, and there are six guys to kill in some "correct" order, then I'm gonna get frustrated and bored trying to painstakingly pick them off as quickly as possible and hope it's the correct order or have to do it all over again... it's the gamers equivalent of when my high school teacher caught me running in the hall and made me go back and walk.
Bad. Needs some kind of orientation pointer, I kept moving my mouse off the flash screen, but couldn't tell because I had no pointer... Didn't enjoy this very much.
