Squeeze Box (thing)

Very unique Atari 2600 game. You play a convict who is attempting to shoot his way out of jail. Not by attacking the guards, but by shooting the walls away from you. The walls of course move steadily towards you until you are crushed. This game is easy at first, but quickly ramps up in difficulty to nearly impossible.

This game is valued at around $8 USD. Games with boxes and manuals are worth more.
