Only one flaw
This game is GREAT!!! The visuals are crisp, the music was enjoyable and the constant life increasing, score multiplying perk of chaining kills gave me a purpose each level other than getting to the end. The only flaw I see here are with the controls, as everyone else has specified. I wish you could have the freedom of choosing your own control scheme, seeing as I personally felt using the space bar to jump very awkward.....what about the "UP" arrow key or "W"? All in all, time well wasted....definitely worth a try. :)
