While looking into /usr/games/hannah being setgid (see separate bug
report) I noticed that it uses /home/$USER/.hannah, instead of ~/.hannah
(or even $XDG_DATA_HOME/Hannah). This is usually right for most Linux
systems, but it isn't correct for all installations/users.

One possible solution upstream would be to use

    SDL_GetPrefPath("FatHorseGames", "Hannah")

for new installations, matching the path it already uses on Windows. On
Unix, this would usually expand to ~/.local/share/Hannah (ignoring the
vendor and using only the app name, as is conventional on Unix) while on
Windows it would continue to be %APPDATA%\FatHorseGames\Hannah (with
both the vendor and app name, as is conventional on Windows).

Ideally it would move or copy the high scores from /home/$USER/.hannah
to the new path, if present.

Or, failing that, it could prefer to use $HOME/.hannah/ instead of
/home/$USER/.hannah/.
