New engine pushed: 'q' is reserved for quitting
-> user can't assign other action for 'q'

New game data packages pushed: They depend new engine. And they have new default key values, which do not use 'q'. (if you have already played game, your key settings have in /home/user/.alephone/*.Preferences )

Btw: Marathon1 is released on 1994, SDL-version is newer.
