Hi Gürkan, thank you for maintaining the Supertux debian package. I installed it in a current debian testing system and found that it is missing the desktop file. Without this desktop file Supertux is not visible for normal users in the KDE/GNOME menu.
Please take a look at the attached desktop file. I would be glad if you could include it in the official debian package as /usr/share/applications/supertux.desktop This fixes debian bug #305334. Greetings from Switzerland Ronny Standtke
