Don't worry friend, at least you have something to show on WebGL, this is an advance, I hope you the best in your shooter game, I have one shooter game upload here in Itch.io, its name is "The quest of Sosaria", it is not multi-player, a great theme in this moments, but it was my Jr Programmer final course project, it is not on WebGL because the weigth of the game. But you can download it from my page on itch.io: The quest of sosaria, the time travel gate II by Mikesquallmx, my idea is to create a prequel from Richard Garriot "Ultima" game, where a doctor Wagner scapes from our time to the middle age becoming himself in Mondain, that will explain why Exodus was a computer in the ages of Sosaria. That was my idea for the Unity Jr Programmer final test. It is complex to create a shooter game, but I recomend to look videos from Code Monkey about the shooter games, he has very interesting ideas about aiming and shooting in that kind of games, he help me too much in "The quest of Sosaria" friend. Good luck!!
