It's a very neat little game. Apart from the last two levels the puzzles where never nearly that challenging. The only difficult part of the game is getting the timing of the robot sorted out which wasn't really made clear. But I really liked the concept and the graphics were brilliant. I loved how everything started to shake as the speed increased when you completed the levels, too.
It's a bit of a slow game. Seems that once you've unlocked the purple blobs that there isn't much more to do.
It seems to be a game where the best thing to do is find something else to entertain yourself whilst you earn more money to buy more blobs.
