Pretty cool idea, though I think the ball physics need a bit of work, it feels like it sends at the same angle no matter where it hits the paddle, and can sometimes send straight up underneath an unbreakable block with means you're forced to lose. Also, just an idea, turning the concept on its head could also be cool, where hitting the blocks causes the ball to grow and you have to carefully balance its size with your health. Just an idea, though, still pretty neat, and with more time it could be a really great version of breakout!
