LBreakoutHD normally installs a flat-text database of high scores:
-rw-rw-rw- 1 root root 1 Jan 1 00:00 /var/lib/games/lbreakouthd.hscr
This world-writable file has been omitted from the built package. On a
single-user system, the first instance of running the game (as a
nonprivileged user) will create the missing file with safe permissions,
and no further intervention is required.
On a multi-user system, only the first player to launch the game will have
permission to modify the high score list. To allow a shared modifiable list of
high scores, you must first recreate the expected file as follows, and add
each user to the "games" group.
chmod 664 lbreakouthd.hscr
chown root:games lbreakouthd.hscr
