This is a perfect scrolling platformer engine. Use left, right, and up arrow to jump and move. This project is also quite simple, as for it uses only 5 scripts and 2 sprites. Inside, it is customizable, such as the levels, jump height, movement speed, and more. You can even make it so it is a 4 way scroller or just a regular platformer. Only thing this lacks is you can see upper tiles on the y coordinate when you have the y coordinate set to 1. Play a version with a test enemy AI: https://scratch.mit.edu/projects/276293400/
