Be the change you want in the world -- did you see the level editor controls at the bottom of the game page? If you're interested, put together a level with some challenge to it and post it here as a reply (check the web console for the level dump). I'll put it in the "final" version of the game and give you credit! I'm afraid I was mostly just trying to get the thing to work, so puzzle design definitely suffered. Thanks very much for giving it a whirl!
