I suggest the Flatpak version.
Oh...huh. I meant which of the ones on the itch page.
I guess for the flatpak version I'd need to use a web browser on the steam deck? There's an install button but it asks what distribution I want but doesn't say which of those is for Steam Deck and there's a LOT to choose from. I guess I'd prefer to do it how I usually do it: just download a file onto my mac and then move it over to the Steam Deck on an SD card. Usually I just use the windows version.
