It works great, but it's just too difficult for me, I'm not that patient anymore to practice it seems. I quit just after the guy saying some numbers. The cannon part after it got me quitting. It's me though, the game works flawlessly!
Oh, and I agree with Thrustball on this. It's just really annoying to do movement and actions with the same hand. I'd rather do movement with arrows (right hand) and then do the actions with (for instance) Z and X.
