Green Flag. Arrow Keys to Move. Z to Jump.
Credit to @slacksupplies for the original engine. This is just a remake because the code was messy plus I made it more simpler. (made it less then 175 Blocks, compared to Version 3.5 which uses 444 Blocks). Also removed things that weren't needed. You have to add things like Actual Collision, Animation. Sound effects, Moves yourself.
