The problem with multiplayer games in jams is that there probably won't be any players, and so happened in my case.
Though I couldn't try the combat, it's an interesting concept and I think it has potential.
It definitely needs some improvement on controls, make the movement overall slower and slow down the player in mid air when he stops pressing the movement button (or it feels like you're being thrown around).
The gravity shifting in my opinion would be better if it was relative to the player's current gravity (so if I'm upside down and shift to left, I expect to go to the world's right) and rotate it before the fall, or smoothly during it.
That said, I hope you'll keep working on it after the jam, I'm interested to see how it will be. Good job :)

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
