Hello!
We are very excited for our next update which brings some major changes and improvements to the game and demo. It is not quite ready yet but it is not that far away and until then some adjustments will be made to give a more accurate picture of how the game is to play.
So basically: Big update is coming soon and the demo will be disabled until then because it doesn’t reflect the current state of the game.
Also, as you might have seen here on Steam, there is new artwork for the game! It was made by the talented Tower Junkie Art, you can view their other cool post-apocalyptic artwork on their artstation page: https://www.artstation.com/towerjunkieart
