It's a great game.
I don't really like the music, but it works well for the game.
Fantastic style, creative and challenging, good graphics, and just fun to play. This is the kind of game people should strive to make... because games should be fun.
There is no doubt that this title delivers.
The only complaint I have is that I've got a mousepad, but that's my computers' fault... and I'd say this game is flawless.
