I like this game. I really do. The music is nice, and the game is so simple, yet enjoyable. Levels are pretty hard though, and game itself is pretty short. I'd wish for a longer experience and maybe even possibility to create own levels and share them with other people. Block such as moving or disappearing ones, would be also cool. There also seems to be a glitch at one level, where my block kept spazzing around the level and then getting randomly stuck into that orange acid kinda thing.
Overall: Game is nice, music is cool, idea of being a block, that helps a hero to reach other end is unique, and controls are smooth and response without any problem. The glitch should be fixed though and more content should be added.
Rating: 4 picos and 4 stars.
