That unblock me is really cool. On your suggestion the wife and I wound up playing it for an hour or so swapping back and forth. We got really good and quick at it solving a lot of puzzles within 30 seconds. Was a ton of fun getting into a competitive kind of style.
Slice It! and Bubble Blast 2 are pretty cool. Slice It! doesn't appear on AppBrain for whatever reason, but it is in the market and a very cool little game.
