This game is about running out of space on two levels: the gameplay level has you packing your cargo full of illicit goods, and the punny level has you running away from space cops (not implemented). There were many features that I didn't get to, but that's life I guess.

Move around with wasd or arrow keys. Run into cargo to pick it up. Once it's picked up, it needs to be arranged in your cargo bay before you pick up anything else. Move cargo around with your mouse. Move it into your cargo bay, or dump it by dropping it on the red triangle.
