Thanks! I hope to have more time to do the next one. One thing that I got out of this, is I decided to get heavily into phaser's state management system. So I ended up creating a comprehensive tutorial as well that exhaustively goes over the process and additionally I include a lot of javascript best practices I've picked up over the years.
The tutorial and source code is on github here: https://github.com/MattMcFarland/phaser-menu-syste...
The final product is located right here on itch: http://mmcfarland.itch.io/phaser-menu-system
