ok, so this is a maze generator. it generates a maze but it will only show you the blocks around you. simply press the arrow buttons and you will move in it's direction! cool right? also, you can switch characters by touching them. you can study the code so you may use it in your projects.
there is a bug that whenever you are at the far right, and when you move right, it will scroll to the far left instead of not moving. please tell me how to fix this in the comments!
