BallBall Babbaballoo!

I made this game in 48 hours for the Ludum Dare game jam #34. The theme was "two button controls." You can see the original submission and comments here, and the source is available on GitHub. It features a green ball, perpetually bouncing up and down.

Use left and right (or A and D) to move the ball back and forth. Press both at the same time to speed up. Dodge obstacles, and go for a high score!
