aside from one really crap level(don't know if that was on purpose or not) the controls aren't all that smooth, the graphics are compressed on normal sized screens, and the overall experience... not impressive.
eh.... three stars. cute, fairly good gameplay(though my crossbow locked into automatic fire, what a pain in the arse.
the friendly fire is a nice touch.
the little touches of animation, like how the hand on the severed arm keeps twitching the entire time you have it, are great.
and honestly, i was wondering what that extra present really was, when the lights went down...
