This is a mario movement system. All arrow keys work in this system Move around, Left and Right and you can jump as well, plus crouch. (this crouch is not from the game original, but was from me) You can also skid around The goomba has armor now so you have to crouch and punch the goomba *its automatic punch*
Me for the code and costume setup but Nintendo® For how Mario looks like. (Mobile still on progress) you might face the collision bug where you go through it on the left or right of the object
