My wish for an improvement would be to be able to control the character's shooting direction with the right-hand side thumbstick on my PS3 controller, then it would totally be possible to play the game with it. As it is, everything else worked (movement, shooting, gold distraction), but if you can't direct your bullets, that's not enough.
(As for reloading, it does reload automatically, doesn't it? Adding a defined reload-button on the gamepad would be easy to do though, while adding the thumbstick for rotation...)
