Nice :-)
Would it be possible to allow an option for the fire key to be '5' on the keypad? I think that would make it much easier to control.
Maybe I should get one of the joystick adapters. I'm terrible at controlling games with keys.
edit: Actually, I've just realised you can get diagonals by pressing two of the other directions, so I can use one hand with my fingers on 8,6,4,2 and my left with space. That's much easier.
