Because I accessed it through the itch.io launcher, which ordinarily has downloadable files to run.
I see. Well I'd ditch that launcher then. That isn't even a launcher if it's just giving you files to launch yourself. I knew itch.io had a launcher (because of gog galaxy 2.0) but didn't realize it was that trash
Ditch it come to the web-side.
Oh my god, this is epic. I actually downloaded a game and now I have all these xml files with all the constructions etc. This would help a lot when making decisions during Impossible difficulty. Maybe I could even figure out how to run it with which local server and play it offline.
P.S. As for you - if you downloaded a game via launcher then run it via launcher.
