I might be up sh*t creek but I'll try and post anyways.
So I played 4 hours of the Demo on my Steam Deck (absolutely love the game and hope you go far with is) and  got the v0.2.0.1 version but something is wrong. The opening screen isn't in English, and nothing happens when I select "English" in the starting screen. If I start the game anyways it just freezes.

I ran the v0.2.0.1 version on my windows 11 PC and it runs like normal.

It sounds like this game doesn't support Linux so I understand if no one is able to help, but if anyone have any idea how I can get the update working on my Steam Deck that would be a huge help. 

Thank you

Just as an update, if I move the game file to my SD card on the Deck, I see the issue I reported. But if I move the game file on the Deck it runs.  So my issue could have something to do with the pathing, or me burying something. Going to play around with it some more.
Thank you,
