Cool art. Got hit a couple of times before I figured out where I was. Then I found out that the top right corner lets you completely dodge the deers, spiders and almost all of the dogs and people attacks. It was a cool knowledge-based touch, whether it was designed or random. I don't think I would last long if I had to dodge them fair :)
Wanted to see the bad ending, so I lasted for about 15 waves. Nice experience playing the game, even though the power doesn't play that big a role in the gameplay.
