Since proton runs each 'windows' game in its own container, by default the 'real' app doesn't get access to the save files in the demo (I assume there is some way in the steam dev api to change this - because I've seen it work fine on other games).

Here's a work around. Run this to copy all the saves from the demo appid to the real game app id:

cp -a ~/.steam/root/steamapps/compatdata/2822250/pfx/drive_c/users/steamuser/AppData/Local/StrikeTheEarth/Saved/SaveGames/Slot* ~/.steam/root/steamapps/compatdata/2541530/pfx/drive_c/users/steamuser/AppData/Local/StrikeTheEarth/Saved/SaveGames

#

(i bet the steam dev console includes a way to map cloud saves by appid which would be the 'right' fix)

Good breakdown. I didn't catch this as one of the Linux playtesters as I didn't test the demo save porting

Confirmed this worked, thanks @shut hornet
I will note that some installations might put steam directory in a different path, but worked with with Pop!

I think its ~/.local/share/Steam for the other common path, at least on my distro

What distro? I think the Steam Deck follows this as well (verbose: /home/deck/.local/share/Steam/steamapps/2822250/pfx/drive_c/users/steamuser/AppData/Local/StrikeTheEarth/Saved/SaveGames/).. but I don't have one to verify.
