This websocket server was created specifically to handle concurrent clients of tww-rando-tracker in order to enable co-op tracking.
Take a look at the Wind Waker Randomizer repo here: https://github.com/LagoLunatic/wwrando/releases
Used when multiple clients of wind waker are synced together and playing the same seed. All players share location checks and found items.
Used when players are playing individually with the same seed. Items are not synced and each player requires checking locations individually.
