I like what you have going here. - Leaderboards and or high scores - Challenges, like a mode B or something. Defeat 10 of X. Fast ball. Short ball. - Up your art. I like the game, just not the look. - Hard difficulty for people that have played before. Even starting on round 5 or something like that. Tetris and Dr. Mario had things like that. - Geometry to the ball to predict better where it will bounce. I think you have it right now to bounce toward enemies when it ricochets off a wall....
