The new version of the demo takes over the old one in Steam, so be sure to reinstall it. Version 0.7.0d is what you're looking for, you can check it in the top right corner of the main menu.
The new demo may not look too different from the previous one at first glance, but it includes a lot of refinements and new systems, albeit some of them are hidden under the hood. Of course, the game still needs polishing, and it seems our list of planned fixes and improvements never runs out. We will be updating the demo in the coming days, so bug reports and any other help from you guys will be appreciated tremendously. After all, one of the goals of the new demo is to catch as many issues as possible and prepare for the Early Access release properly.
Meanwhile, we hope you'll have some fun!
Thank you!
