Oh, I didn't even expect that my little project on the game Jam could interest someone so much. It's nice to read.
I'll just say that I'd really like to turn my "Herzog of Solitude" (I know that in English it would be "Duke", but I prefer the German version of this word) into a more complete and finished work, and then translate it at least into English (and all this will take a lot of time). But if you are so interested in learning a small piece of history between the Hellish Herzog and a brave mortal - who am I to argue with your zeal?
As for the problems with launching - please forgive me, it's purely my fault. The first serious work with Godot, and the fact that it doesn't work is just a problem of my clumsy hands. The game itself needs to be completely remade. Because damn - a novel without the ability to save or even rewind a line - that's terrible. And that's only the top of its problems.
I have only one question - did you download the version for Windows or for Linux?
