This is such a simply designed yet intuitive game that has done well in the combination of both 2D and 3D visuals. The reward is a very nice touch to the game and the open-endedness of the game leaves us wondering if there is more to it.
I think that other than the first mode having the instructions, the other modes can have the same set of instructions replaced by a ready? go! instead.
Would have loved to try this game more but it's not very friendly on lowerend PCs even on the lowest quality. The controls aren't the easiest to understand and I had to mash the keys around to work out the gameplay. A key combination explanation page would be nice.
