The Lone Chameleon is now available on Steam. It's a longer version, with a lot more levels (some rather easy, some really difficult). I hope you'll like it :) http://store.steampowered.com/app/808580/The_Lone_Chameleon/
Quick update to say that I decided to drop the greenlight campaign and give the full game for free. If you downloaded the demo, you should be able to recover your progress by copy/pasting and replacing the save folder in the new game. So the current download link is the full game and not only the demo. I also added the Mac version to download.
If you liked the game, don't hesitate to share and contribute in any capacity on the itch.io page of the game. Enjoy!
