Marioball!
I saw a review were someone referred to this as a Mario clone, and there's definitely a comparison to be made, but really only for the coin-like profusion of diamonds. Mario isn't the only one that's done that theme (Sonic, etc)and it's not a bad idea.
One minor gripe I had with the game, and basically the only problem, as I saw it was the way Ballman forward-jumps. That's really awkward and feels like a lack of control for the player. If it had the same kind of momentum control that Mario games do, that wouldn't be such an issue, but jumping in place would probably be an easier fix.
