I tried pressing R before doing anything, still can't use S or D. Tried any combination. S or D just don't work for me :O Not holding in two at the same time.
That's weird. Do you have QWERTY keyboard layout? I don't know why it wouldn't work. I think you can DM me in Discord (RedTeapot#1960) if you still want to play it, that thing is faster than using comments.
