I think the tutorial said something about reviving the Boingz by blowing into the mic.
Anyway, glad I gave this game a try. It is really, really cool. There are some issues with touch detection, and the little dudes often end up in their rolly polly form when I don't mean them to. But the game has a lot of really cool stuff going on based on the fairly simple but innovative idea of using the smaller Boingz. It's a shame this game will likely get overlooked by most.
Reminds me of Toki Toki and March of the Mini rolled up into one game.
