I've always loved this game, It's simplistic, it's got replay value, and you don't spend an hour learning how to play. It's a casual gamers dream, I'd say. My only suggestion would be to have a fast forward button, I've found myself waiting long amounts of time for some stuff to align correctly! And also, if it'd be possible, maybe there could be a free-play mode or something to where you can just build tracks with unlimited sugar, with maybe a gravity changer. I'd waste a bit of time on that =p. Great game, 5/5!
