Answer 3

First of all, you should know a little of physics for the collisions, when the player jump etc. Also, it requires canvas, as it is a simple game. Mouse and Keyboard events for each player, so I recommend you to make a Class Player to make the 4 object players, for make it online, actually I don't know how but you can look it up it shouldn't be difficult to do.

Answer 4

Thank you for the responses.
I already have my own game (a card game native to my origin). I have it written, is actually pretty solid and I would like to make it playable online so I can battle my buddies.
I did some google research but things looked overwhelming.
The only result that remotely resembled what I'm trying to find was a tutorial to make a multiplayer car racing game which is so broadly written and made no sense to me.
All I could take was that it involved nodes or something (npm, I don't know).
I hope I anybody could shade some light here.
