Okay, strictly speaking this is a Java game and shouldn't be here, but it's SO good that we're making a special exception for it. Sola Rola is a sort of cross between Loco Roco and Toejam & Earl, featuring two blobs making their way across the galaxy exploring planets and solving puzzles in an environment with realistic physics. The graphics, music and gameplay are top notch, and we highly recommend you buy this for your phone. (Incidentally, this Sola Rola has got nothing to do with the Flash game of the same name.)
