The PhaserGames.com site has a new tutorial series on creating an Endless Runner game in Phaser. In part six: "Whenever we decide to develop a game in the office, I usually want to get started on it right away. Of course, the artists need time to develop the artwork. In the meantime, I use temporary graphics or what one of my artist friends calls ÔÇ£Dev ArtÔÇØ. I also sometimes use this on a game IÔÇÖm developing which IÔÇÖm not sure will be released, and donÔÇÖt want to put a lot of time in before IÔÇÖm sure."
