Hi.
We use in Slime Volley some sounds we took in the Ubuntu GNOME's theme which are under license CC-BY-SA 2.0.
Slime Volley should soon be in Debian's games repository. But Debian consider the CC-BY-SA is free since the 3.0.
So we need new sounds that are under a license that's free for Debian people.
I sent a mail to the author of the sounds we actually use but I have no answer by now.
So if someone here could find/create sounds for Slime Volley that are under the good license, it would be great.
The files are s_filet.wav, s_jg_m.wav, s_mur.wav and s_slime.wav in the Modern theme.
