255 is a significant number in computers - a byte can represent the numbers 0 to 255. If you want to store the number 256 or larger, you need another byte.

Write a scene in which your character encounters a hard limit and has to figure out how to get past it. As an example, your character is running down an alley comes up to a wall twice as tall as they are, so they can't walk around it and they can't jump, grab the top, and pull themselves over. How do they get past it?
