Arrow keys to move
So i made this version that reduces lag and bugs by a ton. I used lists to make it that way. To make the game scrolling i would need sprites for the dirt, climbing walls, grass, water, etc. But to keep my changes with the reduced lag, when you add a new backdrop make sure to update the lists in the backdrop scripts and the portal scripts. I explain how to use it in the comments. but generally, you add items to the list in the order of the parenthesis (A, B, C, D, E) Add a Add b Add c etc. I did not make wall detection for the walls in the water room yet. Waiting for sprites, so I can change it then. Don't hesitate to ask me for help on my profile if you don't understand any part of what I did.
