After lots of testing and bug fixing, I coded up an extremely complicated version of griffpatch's scene changing because that was what I could manage. I appreciate how you used your best guess on my character in my PFP it's actually an FNF character named Bandu but when it comes to Role-Playing Games you converted it to more of like a role-playing game style, you draw really well.
The grey rectangles outside of the area of the screen is for telling which backdrops can switch left, right, up, and down. If it covers one direction (example: grey rectangle at the bottom) it means the backdrop cannot go in that specific direction, however, there are no collision checks, the rectangles are just for remembering where the scenes can go
