Steam Cloud saves do not automatically sync between Windows and native Linux versions.
While the game has a native Linux version, the Steam Cloud is configured in such a way that saves will not automatically sync between the Windows and native Linux version.
If you are playing across device (ie. Windows PC and Steam Deck) you may prefer to force the use of Proton so that the Windows version is used on both devices for seamless save syncing.
The game runs natively on Linux since 2020-11-06.
You have to move your savegames.

Infrequent slow downs
After launching with Proton-5.0-9, a Unity logo is displayed briefly, followed by a black screen. You can still hear the sound of the Apogee logo in the background but the game doesn't run. I was able to start it successfully on my system with Proton-5.9-GE-7-ST.
