I gave this one a try this afternoon and was pleasantly surprised. I picked it up because the artwork was cute, but sophisticated, and it turned out the whole package feels that way (a good thing).
Your goal is to squash buggies, as many as you can simultaneously and repeatedly. To do this, you need to press anywhere on the screen to begin generating a bubble around your little dewd. When you release, the little guy hops up into the air and then plummets downward, hopefully on top of a group of buggies. When you hit, a bubble explosion triggers that is the size of your initial pre-jump warmup. This is a nice little risk/reward mechanism, because if the bubble contacts an enemy before the jump, it pops, and you'll have to start again, wasting valuable seconds.
In some ways, it's a hybrid of Sneezies-style chain reaction games and Starball, with the tilt control, combined with a jump system all its own. There are multiple environments, which represent the seasons, I believe. The artwork is phenomenal, the gameplay is kewl, and it has global leaderboards. Nice work, to the devs!
