:) -=- Might I respectfully add that a menu item:
/CREATE YOUR OWN LEVEL/
.. that would be so awesome :) and people could share their puzzles somehow? maybe just wishful thinking on my part but would be super!
This won't be in anytime soon, but yes, I think it would be great to have user generated content & sharing. I currently use hacks to build the levels myself, so it's kinda ugly. But it is user friendly enough (through Unity at least) and the files are JSON, so once I get the editor actually working, it will be easy to share. It's on my to-do list!
