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!
