Before I proceed on the battle engine, I want feedback on if I'm going in the right direction, and if the progress I made matches with @StarWink5000 and @toad_690's visions. Obviously the action commands aren't in place, nor is any controls, just watch the jump animation. Use "v" to show the Scroll X and Y variables, as well as Mario's X and Y.
The Mario was drawn (and animated) by @toad_690, while the goomba and background were drawn by @-JAM58-. Other than the animation code (@toad_690), coding is souly by me. Music posted by @StarWink5000, while I know it's not the "official battle theme," I thought it fit best out of the current OST. For SML, link to studio here: https://scratch.mit.edu/studios/35850128/
