Red Ball, Blue Ball was made in about 6 hours for the May Berlin Mini Jam 2014.

Use your two XBox360 controller sticks to maneuver your diamonds. Touch your ball with a diamond to throw it to the other one!
When you touch the star with your ball, it becomes your color. Let it stay this way as long as possible!
Use on of your back buttons to create a wall, blocking the star and the enemy ball. Only one at a time, and it has a cooldown.
