Fun, nicely done. I have some issues, though.
People complain about not knowing where the ball needs to be in order to hit it. I too ran into this problem once or twice. If you need to view instructions for something like this that should be intuitive, you're doing it wrong. This is an issue that needs to be looked at.
The game is kind of dark and the ball is small and dark as well. I had a hard time tracking the ball most of the time, especially since the explosions are also huge. Breakout is a very exacting game and the fact that the blocks are people, while goofy and entertaining, makes the gameplay lack. I didn't know where I should hit, what I should aim for, and at times I was sure I hit one but realized, no, it just flew right through him.
The idea of the charge up kick is really nice and it works really well but I think everything else is done wrong. You should do some re-designing and design some more levels, too. I would suggest dropping the humans thing unless you can make the hitboxes a little more obvious.
