In Shoot or Rust, you are the pilot of a little repair spaceship and you have to put the blocks back in the wall! But to do this, the blocks must be the right color. Only blocks of the same color can stick together. Your protective shield is attacked by evil alien spaceships. During the attack, you can protect the shield and fix it! You must reach a certain score to advance to the next level. And if an alien shoot touches the top of the screen it's Game Over!
