This is a little proof-of-concept thing for what can be done with my modified form of @easy555's scrolling engine. It uses multiple layers and can be used to make a more realistic platformer. Think of it as Fixed Scrolling Engine Part 2. I will hopefully be using this in a collaboration with @easy555 on a platformer. This was made in about 20 minutes on 2018-4-12. (I already knew what to do as I had made it before on the collab account)
