Overall a good start.
One of the things that I got hooked up on was in level-0/totoral I did not know how to get through the final door to the hub for some time. When I saw the pipe all I could think about was Mario and how you would need to go into it even with the other door there, so I kept trying to jump up to it. It would have been nice to have something to say that you need just the magnet to go up it.
