Decent game. Incredibly short, though. The procedural generation is quite weak, as it just feels like a normal platformer with a random order of levels. As such, I wouldn't consider it a roguelike, because of the lacking generation and the fact that it's too short for permadeath to make much of a difference. The difficulty is also very inconsistent, with some levels (such as the one with a ton of whatever those flying enemies are) being way harder than others. Also, I noticed a bug where sometimes the music doesn't work. The physics are kind of weird, as well. Overall, though, good game, with nice art, nice (but repetitive) music, and decent level designs.
