Pretty impressive from a tech-demo perspective, but I found the game a bit dry and boring at the moment. Again, lord knows I couldn't make an online game like this with servers and all that hoo-hah, so kudos on getting that all setup. But looking past that and playing the game, I just found it to be quite boring.
Don't get me wrong, I did think there were some nice touches like the emote system, and there was an attempt to make some cool combat through various levels and an assortment of guns and power-ups. But in the end, combat always just felt like it came down to just shooting at each other in really simple, unexciting ways: there weren't really any fun abilities you could use to outskill your opponents in clever ways, no satisfying explosions or feedback for gunfire, and the levels didn't have any cool environmental hazards, setpieces or unique charm to them. Felt like the game was overall very janky as well, with weird staticy sound effects and such.
It does look like you are still updating it, however, so maybe it'll keep getting improved upon and I'm jumping the gun: best of luck!
