This game was made for a 32x32 resolution for lowrezjam. Click on the block you want to move. Click off when you want to switch. Up/down/left/right WASD to move the blocks. E and Q to flip the long blocks. The blocks are stickier against each other than against walls. If you think a block is stuck, try tapping it with another block or click off and on. The '!' in the top right corner pauses the game. Game autosaved after every level so you can go back in to the stage select. The boards you have gotten to will be hightlighted with a green dot. The object is to fill the white spaces being sucked out by the evil pixel guy. Every few levels, something else is added. Keep a watch for the changes.
I think I made things a little too difficult on some levels. I was thinking about making a time trial once you beat the game (minus cut scenes) to have a scoreboard. :)
