Hello @Atornity!
I recently completed my first published Godot project / demo which had implemented and modified the original recoil system you had published. I would like to thank you again for sharing your insight and project. Without it I most likely would've been still using my original stiff and rigid "push-camera-up" recoil which wasn't ideal haha.
I made sure to give you a shoutout in my project's credit page and have a video published showcasing it. Cheers!
