Arrow keys to move left / right, up to jump. You can't do anything, I was just playing with animation and slippery movement, trying to convincingly pick a good frame depending on what's going on. Platformer maybe... This uses my standard game framework to keep core timing the same no matter what the system or framerate you're running at. So if you run this in Turbowarp at 60fps it'll look smooth and silky as the core is running at 50fps. And yes I know you can jump backwards.
