I guess it's a, er, 2D platform hack-and-slash RPG. Think the gameplay of something like The Dishwasher married with the RPG-lite elements of Guardian Heroes, although it's arguably not as good as those. The plot's quite interesting in a "watching a feature-length Saturday morning cartoon while hungover" sort of way.
It's one of those games that I really enjoyed personally, but I'm a bit wary of recommending it to others. If you've not got the points earmarked for anything else, I'm sure you could do a lot worse. If you do get it though, don't bother playing on the standard difficulty. You'll either do what I did, and restart halfway through for more challenge, or you'll breeze through by button mashing (which is a shame, as the fighting's pretty good on the harder difficulties).
Edit: Took waaay too long to type that!
