Thanks for the info in the change log. A further question is this the version that you will update without further cost to us or do we have to wait until the game is issued on Steam. I have you in my Steam Wishlist but it shows 2019 for game release. Overall, it is is a very well done game and should do well on Steam.
2019 will see the start of Beta phase and the final release of the game. However if you buy an Early Access release like this one, or the Steam one, each update of the game will be free for you forever, including Betas and Alphas :)
Only Patreon pledgers have an earlier access as well, with a free Steam key if they reach 30$ in pledges overall, plus more rewards, but that's a different thing.
