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.
