I say go for it. It's an immensly satisfying game once you learn to adapt to an unorthadox control scheme. Again, it's unorthadox control, not bad control.
It's a short game and kinda easy once you get into it. 30 dollas, though? Yeah, go for it.
Lots of pure gameplay here. The story is pretty much optional and the graphics and sounds are sometimes incredible.
I would consider this a sleeper type of game.
Any more questions?
