BallBouncer

Small test game I made on a train ride. 

Click to create bursts. Use bursts to bounce balls. Each bounce earns you points. When time runs out, spend points on upgrades for your bursts. Increase size of burst, how long the burst lasts and more health. When you run out of health, the game ends. 

Each level, the number of balls may increase (based on a curve with level number as an input) and the size of the balls decrease.
