Fun game, but the controls are quite infuriating sometimes due to the camera position, would be nice if there were multiple views available. That's also part of the fun of it though and it does get easier with practice. The puzzles are relatively simple but a few are challenging. But some are challenging for the wrong reasons, namely the mechanics of having to solve a puzzle when you can only partially see where the block is moving. All in all it's mostly relaxing and entertaining.
