3 multiplayer gamemodes to choose from. Which one will you play? (NOTE: When the first version with multiplayer included is released, only a partially finished version of the competitive multiplayer mode will be available. Multiplayer will also initially only be available on the Windows and WebGL versions of the game.)
Multiplayer support for the MacOS, Linux, and Android versions of the game will come in a later version of multiplayer.
Yes, that will be one of the options available when you are setting up a multiplayer game. You'll be able to either create a game or join one with the name you entered that has the same maximum amount of students (aka players) you specified, or join a random game (or "random lobby" as you call it) that is not full yet.
