Challenge your friend with this musical memorization game. As the tune gets longer and longer, the last person who remembers his/her friend's tune wins the game.
For multiplayer to work, the hosts need to have port forwarding configured on their routers, if their computers are behind routers. For example, if a player starts the game as the Host using port 16305, then the forwarded port should be 16305 UDP on the router.
If UPnP is supported on the router, the UPnP Tool can be used to forward the port.
