Figure out how Phaser messages and switches between scenes

[JoshuaKGoldberg]

Following #17:

I don't know Phaser best practices and I don't know how to message pass between scenes... in the meantime, made a state.js file that keeps the game so they can start other scenes. I'm hoping there's an easier way to get around this.

Talked to @LinKCoding a bit, who pointed out:

• We can call this.scene.start("GameScene")
• After that, we don't need to keep shared state between scenes
• If we want to message pass from one scene to another

...and pointed me to https://www.codecademy.com/courses/learn-phaser/lessons/complexity-in-phaser/exercises/scene-transitions?action=resume_content_item, which is exactly what I needed for the scene shenanigans, thanks 🙂
