Dear Maintainer,
When playing this game, there are a lot of errors of the form:
Failed to load sound sound/boss/boulder_boss/roll
Failed to load sound sound/common/rock_shatter
The exact filenames vary depending on which map you're on.
Many of these sounds are played before there is any visible effect,
so not having audible cues has a negative effect on gameplay.
I have not investigated whether something is wrong with Debian's
packaging or whether upstream simply hasn't found any open-source sounds
yet.
