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.
