Dont take this the wrong way, but...
This game annoyed me when I first played it.
Its a good premise, simple, engaging, and funny to boot. My problem is that your enemies have the same range as you, and if you dont sneak up on them or move right, then you are dead FAST. Also, if you attack them from the front, they hit you back immediately, and often with more oomph.
Other than that, I really enjoyed it, especially the little quips they spout while attacking. The graphics are smooth and stylized, and the feel of the game is really neat. I'm still going to play it, because tbh, its better than most pc games out right now. Its just really pretty difficult until you get the hang of it. Maybe a little bit more of a learning curve, and this game will be seriously kickass. Until then, i'll be attacking around corners, and dodging fast.
Also, that penny-arcade level is screwed up. You are sick for camouflaging them.
