If you could provide an alpha Linux build I'd love to try and see if what you've got currently works on my Steam Deck (even if I can't personally contribute to making it work as such outside of reporting what happens). I'm too much of a novice to compile it myself. I'm stuck on "The heck do I do with SDL2?" lol. I tried running the normal version as a non steam game on different Proton versions and got white screens.
