Save for the obvious lack of audio, it's a very nifty concept. The controls felt a bit slippery (I was constantly sliding off of platforms by accident), but I never thought I would enjoy climbing on top of a staircase of dead dinosaurs. The art itself was very nice, and with some polish in the form of both visual and auditory feedback, such as a screen shake effect when getting hit/shooting, this could be a fun little game. Good job!
