Thanks, I'll definitely keep working on it. Multiplayer wasn't the best idea indeed. Took me about half the time I had for the jam to get it working properly (through NAT and in browser, the stuff in game was surprisingly easy) plus the player part now. I would try and join as many games as possible myself but I only have access to a tablet with keyboard at the moment...
The camera on gravity will need some more experimenting. I tried rotating immediately but then you lost aim so it was a stupid move during combat. Now you can shift as often as you want during the fall but have to watch where you land.
I try the other movement suggestions for sure
