This is a simple engine. Remix if you want. If you want to change where the player is, go to the only "Green Flag" script and edit where you want X and Y to be. There are only variables in the "Main" sprite
There is no code in the "Level" sprite. I recommend having a basic understanding of custom blocks, variables, and just the inbuilt blocks that scratch already made. I did not have any help on this, all of this was made by me.
