Doesn’t seem to play too good to be honest. If you can’t fire + aim at the same time I don’t think I will be able to enjoy any FPS. Please add the missing button as seen in Beloko’s port videos.
I would like to try your setup but I think that it will not work with the free version, and by looking at the video it doesn’t feel too good tbh, it just seems like you strafe, and shoot while strafing but not while turning.
