Recently converted my old Flash Game into Phaser III. Demo version here. It is a “teaching tutorial game”; use the Dev Console to watch the inner working.
It’s license is included in the newly released book “Phaser III Game Prototyping” available on both LeanPub.com and Amazon (hardback and eBook).
PS: Owners of the previous edition - “Phaser Game Prototyping for v2.x.x” - were emailed a “generous discount coupon” yesterday by email from the LeanPub email list.
