I assumed you had watched that video because you even included the bit of weapon pushback when firing, but it's no easy feat to include all of that feedback/polish and make it work within the constraints of a game Jam. As I mentioned before, well executed!
I've also been on a bit of a Rami binge, in part because of your entry. He very recently gave a small talk at an Illinois university on the etymology of mechanics, though none of his slides made it into the broadcast and the audio is wonky.
