The (alpha) demo will available for free on Itch.io for anyone who wants to test it. There is no set release date yet but I aim for the second week of December.
In what state the demo comes out is still and open question but I keep updating it for some weeks to fix issues.
After the demo (and your feedback) I think I will move back to the closed development cycle until the time is ready for the next demo. This next demo then could represent the game in more feature complete state.
You can find more info about the alpha 1 demo on its dedicated page.
Thanks, - JONI
