Hello! Thank you very much for your very generous support so far! I really appreciate it.
The joystick input should be handled by the Orx engine directly. I'll ask in their support forum regarding your OS and joystick configuration.
As for the footsteps, if you find them annoying you can rename/delete the sound files "walk1.wav" to "walk5.wav" from the "Tenebra\Res\Sounds" directory.
