Blockage 2 is a unique puzzle game in which you have to move colored blocks to their designated spaces. Click on a block to select it, and then move it with the A and D or left and right arrow keys. When it's in the desired position, press space bar to solidify it. Colored blocks can move through other colored blocks, but not solid blocks, which are black. A colored block will automatically turn solid if it is moved into its designated space.
