This must have been fun to make. I think level editors are such a cool tool. It's something you can use in future projects also with some tweaking, you can make full levels in just a few moments. I would like to see this worked on more. I would also work on the character controller a bit. I did get a game over if I stood still to long... not sure what that was about. But all in all, I think this is a very creative project.
