I needed a break from the new Vector game I'm working on, so I whipped up Superstar Combo in a couple of days. It actually turned out better than I thought it would. Some people have been able to score over 300,000.
Shoot the paddle with the left and right arrow keys. Collect the gold stars for points, and the blue superstars for mega points (although superstar pickups only count on a clean run). Each time you make it across without hitting a slab, your combo multiplier goes up by 1. If you get hit, your multiplier drops by 3. Earn bonus points for near misses! Score as high as you can in 100 seconds. The R key can be used to restart at any time.
