Well, that was awesome. Really fun; original, pleasant art style, nice music (could do with a few more tracks, and on that note, perhaps some different scenery). A story might have been nice.
But as its own little package, this is a nice, neat, and fun game. It's a little bit easy to get squished, since it comes out of nowhere. Visually flattening the little guy's sprite before killing him would have been a nice warning. And kudos on not being a bitch with respawn times and game over screens, but why do I have to press a button to respawn? Why not just do it instantly?
It has a mute function, which is obviously good, though it's a shame you can't mute only the music or only the SFX. But that's not a big deal. This definitely deserves a couple of awards, and probably a front page.
