Cannon Blaster starts off with your choice of levels. You have to unlock anything above "Easier than Pie", however. I'm pretty intrigued by the "Clouds are Deceiving" and "Bombs Can Be Fun" levels. You'll drop into a barrel and you have to time when you shoot yourself out of the barrel. You'll go from barrel to barrel, avoiding bees and other baddies along the way. The goal is to shoot yourself into the sun, which sounds like certain death to me but then again what do I know? Cannon Blaster has a lot of levels and it's super fun to play. Plus if you're really good you get to the "Impossible" level at the very end!
