Scenario: Getting an Entity reference

What is the most proper way to get a reference to my GameEntity in this scenario?

Say I have a query like this:

isNewPlayer: {
    components: [ PlayerEntityTagComponent ],
    listen: { added: true }

And a query handler like this:

this.queries.isNewPlayer.added.forEach(playerEntity => {
    // TODO: get existing gameEntity so I can add playerEntity to the gameEntity's PlayerListComponent

How should I get the game entity from ECSY? I have it named ‘game’ but there is no method publicly exposed to get an entity by name.

Is there a better way to arrange this code or am I just missing something?
