This is a big sliding puzzle. Click the tiles to slide them and collect coins to score. You can slide tiles before starting the game to set the board up. But once the clock is moving there's no way to pause it!
Based on a very old board game with a moving alarm clock that followed grooves in a grid of sliding tiles. Theres a couple of nice bits to this. First of all the sliding puzzle is a game all on its own. But there's also the line following algorithm for the clock which uses only two sensor sprites.
