sdddOh no! You are trapped in a world of boxes! Use WASD to move the blue block. Use E to hide the amount of checkpoints. Use Q to show the amount of checkpoints. Use the up and down arrow keys to adjust the volume of the music. Don't touch: black lines, orange doors, red boxes. If you touch the red boxes then the game will reset. If you touch the black lines or orange doors, then you will go back at the beginning, but unlocked doors will be saved. Yellow blocks are buttons, go over them to unlock the orange doors.
