Hey, man. I really liked this demo, but i couldn't help feeling very envious... I'm (coincidentally) making a quake inspired fps, and I also gave myself until Halloween (which was in 1 month, at the time) to get a playable and polished demo. I don't think that I would be able to make anything as rad as this in a month.
The webgl build for what I have is at https://almost-friday.itch.io/thrash. Although super barebones and ugly, I actually have some features that I didn't observe in your build, with rocket jumping and melee enemies being the two noticeable ones. Do you have a discord account? I'd love to see if I can help you out in any way, be it programming, art, or animations.
