So the demo is now publicly available on the Steam Next Fest until Feb 28th. For various marketing (and stat tracking) reasons it's only on Steam for a limited time but preordering it on itch.io will get you the demo forever until the final game is released. Additionally the itch version will give you a Steam key as well.

The demo is a small vertical slice that shows off the main features of the game and what you're generally doing. Feedback/critique appreciated, and let me know if you need any support.
