You're working at the conveyor belt of a box factory and day after day you fold boxes. Something that really drives you round the bend, especially when at a certain moment the conveyor belt runs wild and starts moving faster and faster! Suddenly everything goes black. The moment after you come to your senses in a cubicle world: it looks like a box. The cube can turn in all directions. Try to get out of that world by moving to the exit (red-yellow striped door). You'll have to take quite a lot of obstacles and you can also grab beautiful gems.
Use the left and right arrow keys to walk and the up and down arrow to climb ladders. Use the spacebar to jump.
