You know, back when I was playing this, I was annoyed at not finishing the world, but I think I'm being unfair on myself. Up until now, when doing mario hacks and stuff, I always try to keep it around two levels, because I think that's a good rounded number for these sorts of things. It's going to be annoying in a way, to fit this in with everything, but I shouldn't push myself too much, as the experience isn't as pleasant for anyone.
