I'm very interested to see how this works with more complex courses! The current course is a bit straight, but with some twists, turns, obstacles and moving doodads I'm sure you could make some interesting levels! I think tho that any levels you do make should be fairly short, the current level took a while to construct a solution for, and then when actually playing, it was rather slow. If the level was any harder, I'd imagine it taking a while to iterate and improve, so I think shorter levels will be more engaging. Neat game idea, I think it's got a lot more potential still to be explored!
