First there was Pushmo, then there was Crashmo and now we get an exciting twist on the formula in Stretchmo.
You can download the first seven levels of Stretchmo for free to try it out and see if you like it, before purchasing one of various attractions which contain several more levels of varying difficulty. The addition of stretching seems like it could make the puzzles considerably more challenging. A launch trailer released for the game shows off the new mechanic and explains the various purchasing options.
