1) I've been working on BF'88 for a while, and I think it's time to share everything I've learned about gamefeel so that when this project is done, someone else can do something even cooler. First, none of this would be possible without the amazing work by @jwaaaap & @tha_rami. 2) Seriously, the first step is to watch the art of screen shake and do literally everything in that video.
Everything described is in BF'88, and having those tips available was crucial for the further explorations I've been doing.
