This is a super simple, networked pong game, where the processing is handled by the server, and the client only sends input and receives position updates. It is single-player - the server simulates the second player/bot.
cargo run -- server to run the server
cargo run -- client to run the client
On the client, UP/W key moves the left paddle up,
DOWN/S key moves the left paddle down,
and SPACE/ESC resets the game.
Networking is done with quinn/tokio. Graphics and input is macroquad.
