Multiplayer framework

The framework of multiplayer is completed with the following components:

• Creating and joining public or private lobbies, with or without password protection.
• Syncing player data, including character selection.
• Remote multiplayer session through Unity Relay and Netcode with GameObjects (NGO).

Lessons learned:

• Test each component separately and thoroughly first to avoid long and unnecessary debugging.
• Network objects should be small and compact to avoid spawning issues with NGO.
• It is a bad idea to do p2p multiplayer with WebGL.
