It works...
But with this being such a basic game design, that is all over the place, not even featuring functions that are common in these types of games today such as power ups, you might want to spruce it up a bit so that it can really shine. As is, though it works fine on a technical level, this is so unimaginative that just above blamming material for me.
Suggestions:
*Power ups in this kind of game are a must, to keep a player on their toes!
*Faster physics
*As something different, perhaps a 'ship' that is not flat, something harder to control where the ball will go after bouncing.
*Something more than basic block graphics. With a game like this, you can get really creative and make it stand apart even with a simple technical design. For example: A wizard player blasting an orb that keeps knocking off parts of a zombie. 1 level could be multiple parts as you wear the undead down to the black magic that is animating it!
*Sound effects! I want to hear that I'm doing damage! This could be shattering noises, explosions, or in the case of the example I just provided: wet squelching noises!
