Like others said, this is definitely one of those meme party games that you play with friends and everyone does badly but that's the point. Awesome that you set up netcode, maybe you could run a workshop on that someday, it seems to be a hard task for just about everyone. I think it was a good design choice not to also make the direction of movement reliant on arm facing direction but make it the way you were looking, as anything else would be genuinely unplayable. I guess not being able to see the current location of your arms is by design, though maybe there could be an indicator or something to know approximately how to move them in sight - I am also the motion sick kind, so I can barely even look around/down before getting dizzy. I think adding more options for combat would reward higher skill levels of aiming, such as specific targets or different damage based on parts of the body, just so that the game isn't whoever gets a hit first probably wins the encounter - balancing these kinds of games is hard, but there's definitely a lot of potential here to encourage good aim and improvement.

I think this is the first time I've played an online multiplayer jam game! I get motion sickness from first person games so I could only play for a little bit, but this is really well made! The visuals and sound effects are pretty minimal but I appreciate that to be honest, and I think they're well done for what they are. Having to switch between head/arm movement didn't take as much time to get used to as I thought, and I can imagine a lot of tactical strategies that emerge from that mechanic. If you decide to keep working on this I'd love to see that mechanic developed more - I don't know if this is what you were going for but I interpreted this as like a rage game, which I think has interesting implications especially for an FPS. Maybe your head can be totally separated from your body or something like that. 

Great job with this, I love the idea and as bbcc said it isn't as infuriating of a mechanic as one would expect. Not sure if the parkour options were fully intentional, allowing player to be essentially above the map, but hey at least if theyre up there they're visible and it isn't a bug where players can hide in the floor or something. Overall great job and it's really impressive being able to set up multiplayer within the scope of a game jam, definitely had a fun time when it worked properly.

Interesting concept! Honestly, the mechanic isn't as frustrating as I thought it would be, but also I'll need to actually test it out with other players, but I'm guessing that it'll just make playing with friends extremely funny (the really dramatic bullet spread will probably add to that lol). Amazing job setting up multiplayer in a jam game btw.
