It's basically a depraved grindcore-soundtracked running shooter, and it's suggested that the music be turned up to ear-bleeding levels before playing.
Warning: Not sure about the music (I can only imagine, though), but even the text that shows up on your screen indicating which level is up next (which seems to be random) is NSFW. I guess the music is somehow necessary to playing the game, but I had my speakers off because I'm at work (heh heh).
My high score: 210448 points in 25 minutes 2 seconds
My low score: 0 (I automatically went for the WASD keys instead of the arrow keys, didn't figure out why I couldn't move until after I was dead.)
Well, yeah, kind of mindless, but fun. The art direction is pretty good, though. Again, not sure about the music...maybe it ruins it. I'll listen to it when I get home.
