It would be way helpful if the items had a magnet to them, so you didn't have to hover so long. It's frustrating when you think you've dropped something over the top of something else, but then it snaps back to the belt and you're like, "NOOOOO!"
I would have like to have had more control over the Bison's movements, rather than just controlling his undie rockets and whatever powerups I received. Other than that, I loved loved loved this game. =]
