This is what steam outputs to the terminal when i start the game:

Distro issue: https://github.com/NixOS/nixpkgs/issues/155278

Like with other steam linux issues, the most elegant and portable solution seem to be to target the steam linux runtime.

Try checking if some of these libraries are missing on Nix for now; There's not much documentation about this class of error.

Try also running it outside Steam, if possible with a debugger, it helps if no one else has a clue (as seems to be the case)

Launching the appimage manually from command line like this works for me on NixOS:

appimage-run ./SuperTux.AppImage

Launching it through Steam however gives the same error:

dlopen(): error loading libfuse.so.2

Did you try setting the launch parameters for the Steam game to appimage-run %command%? This might work around your current issue, even if it is not a solution.
