The game should be player on a local network.

• Build Server scene and run it on a computer,
• Build Client scene and also run it,
• Builds should also be available in Releases section on github,
• On client, press Connect button. Client should detect running server automatically and connect to it,
• If the button doesn't disappear - try again. UDP message could have been lost,
• When client connects successfully a player should spawn on server and client,
• Connect more clients from different computers if you want and play the game.

• Authoritative server,
• Client-side prediction and server reconcilation,
• Entity interpolation.

I've tried to follow some concepts from Overwatch's netcode, so client runs ahead of server and changes its tick rate when it goes out of sync with server.

Use W, A, S, D keys to move. When player is near the ball press SPACE to kick. Place the ball in opposite color goal.

• Handling disconnections,
• Not using long strings as message headers. It's a waste of bandwith but I did it for convenience,
• Using FixedUpdate for ticking client and server may not be the best idea. Research possible better solutions.
