Blocks are used for building, playing, and learning. In this game of blocks, the objective is to remove the specified amount of blocks while making sure the sprite isn't on an inactive (gray) block. Some of the blocks spin, move, and try to get the sprite to fall below the line. Do not let the sprite fall below the line or the game is over. The sprite's movement can be manipulated using the arrow keys and the blocks can all be removed by left clicking on them, but be careful when removing them, because it might just cause the sprite to fall in to oblivion.
