Use the, left and right arrow keys to move side to side, And use the up arrow key to jump. If you press down whilst midair you'll do a quick-drop. If you wanna see inside this engine's code and completely yoink some of it go ahead, just know I only really accounted for what would be shown in this little project. So some adjustments will need to be made if you wish to create an actual game with this. Just give me credit for making the engine. I might use this properly in the future, but for now it'll do!
P.S: ignore that I used the built scratch sprites, I was feeling lazy -mario123joe If you lag at all I'd recommend you use TurboWarp to run this: https://turbowarp.org/1262689914?size=640x360&stuck&clones=Infinity
