Ok, the first thing this made me think of was Pac-Man. The setup is a little different, but's it's similar. The student is a shirt (hoodie) that has to walk around eating numbers that have a certain digit in the ones place or tens place. EXAMPLE: Let's say the directions are 4 ONES. The player has to find a number like 34 or 64 to eat. While you are doing this, you have to avoid getting eaten by the ghost.
