Have you played it? You really should.
It's a randomly generated action platformer with about a bazillion and one random events, treasure, powerups, and challenges. Be warned, you will die... a lot. Learning about some of the less frequent challenges is often humorous, because of the sudden unexpected death. Sometimes you may want to pass up rooms you know will be difficult based on the surrounding terrain.
One quibble with it, I wish there was a way to recharge your hearts. So far I've not run in to a health replenishing item, so it's four hits and game over. But again, most of the fun of this game is in the discovery. I played for nearly an hour before ever reaching level five, only to find that the game changes things up over the long term as well.
Now, to finally go about installing the drivers needed to use a PS3 controller on my PC. This game is worth the trouble.
