paulscottrobson It's just a game where you're a robot, you press a button to change you're color, you need to have the color of the block you want to shoot to destroy it. If you shoot a block thats NOT the color of your robot, you lose, and you're timed, so lets say level 21, you'd have 1 minute to complete level 21.
And you need to dig through the blocks to be able to shoot a small golden block (that works for all colors when you shoot) to win the level.
