There's a new demo out, even if you've played the 1.0.0.0_O Demo , I highly recommend you check it out! The last demo is from 2+ years ago and there's been about 60 or so updates since then. The new demo is built from the most recent version of the game with a few things removed to keep the demo cut down from the full game. More content updates coming soon! The demo will remain on this version for now, I will try to update it every few months. 

Enjoy!
