Looks and sounds good, runs smoothly, so well done!
Multiplayer games are always a bit of a risk with a game jam. It looks like there's a ton of different weapons and mechanics implemented, but it's kind of tough for me to judge if it is fun without being able to play against someone else... from some testing against myself it felt like maybe the weapons I tried were a bit underpowered and would need to be stronger (laser at least felt weak, flamethrower seemed to do better against better armor). Probably just needs a lot of play testing and balancing to turn into something fun. :)
