This game can be played either with the keyboard or the mouse. The goal is to get the green blocks to the finish. Use the arrow keys or click inside the level to make the blocks fall left, right, up, or down. All blocks must fall until their path is blocked. Darkened blocks are stationary. The types of blocks are listed below, but you'll learn them as you go if you play the game.
In some levels, it is necessary to destroy certain blocks and in others the blocks need to be preserved in order to reach the goal.
