GNUjump is a clone of the simple yet addictive game Xjump, adding new features like multiplayer, unlimited FPS, smooth floor falling, themeable graphics, sounds and replays.

Following things don’t work:

– Don’t try to change the theme in the game. It will lock up. In mini menu you can still quit it with the Pandora button, in XFCE you have to reboot.
– Some other menuoptions do the same, mostly graphic options. If you want to try other themes or options, you can enable them manually in the config file in appdata.
