Control the spikes so the ball doesn't hit them - a nice inverse of a popular mechanic.
Yoyo Developers released this game a while ago, but for some reason I missed it - and it's a fun little app, so worth mentioning now :) "A highly addictive and simple game where bouncing is the key to survival!
In Bounce to Dodge, a small ball bounces across the screen. It's your job to control the spikes so that the ball doesn't hit them! This simple, arcade style game is great to play anywhere, anytime!"
