ops! sorry about that… it’s a silly bug. It looks for these options under “ctl” not “controls”… rename the section to “ctl” and back-up the file, because unfortunately it will overwrite it with the wrong name again on exit…
edit: I prepared a patch for the windows version which fixes the issue. Run it in the same directory as the game executable, and it will patch it to use “ctl” everywhere. Delete your game.cfg and run the game to re-create it correctly, then edit it at will: http://nuclear.mutantstargoat.com/sw/games/deeprunner/releases/deeprunner_patch1-win32.zip
