I like your take on BreakOut. BreakOut is a classic game, but making the arena circular was a great choice. Having to question whether the ball will go through a hole in the blocks or rebound back at you is a simple wrinkle that makes the game more interesting.
It took me a little bit of time to adjust to the controls. I was having a lot of trouble with level 1 because I couldn't inch the board around as precisely as I wanted. Once I beat the first level, though, something clicked and I was able to finish the rest on my first try.
