Push bricks to trap all the monsters! Can be played in multiplayer mode with a unique twist. A single player mode is also available. After level three of multiplayer, one player can only push bricks vertically while the other player can only push horizontally. I strongly suggest you get someone to play multiplayer with you--it is much more fun to play multiplayer.
