Welcome to Tetraduel! 

This game has singleplayer as well, but it's not as fun.

This is my first multiplayer game, but it works pretty well. There is no server setup so you will have to use playit.gg to setup non-LAN multiplayer.

Multiplayer does not work in the browser, you must download the game

For host:

Set the Port but not the IP, if you change the IP either type in 'localhost' (without quotes) or if you know what you're doing, your device IP.

For joiner:

Set the IP and port to whatever playit.gg gives the host.
