Bouncy Bug is a pretty fun game app for the iPhone and the iPad that is free for a limited time. Normally, it is $0.99. You are a bug that is trapped in a world of jello trying to escape. You have to collapse each “bubble” in the jello by eating up all the fruit by bouncing off the “liquid-y” jello walls by tapping the jello walls. The physics of the game are pretty interesting as it is very similar sensation and feel as a simulation of bouncing on a trampoline. There are lots of levels of play to enjoy and play. Even though it is easy to learn to play, the challenge is figuring out the timing and angles of the bounces.
