From Josh Morony: "Recently I wrote a tutorial on building an infinite climbing game in Phaser which borrowed some concepts from Thomas Palef’s tutorial on building a Flappy Bird clone but kind of flipped it on its head a little bit by generating the game vertically rather than horizontally.
This game is going to be similar again in some ways because it will also have randomly generated platforms with holes that the player has to get through, but it’s kind of going to be more like a Flappy Bird cross Jetpack Joyride hybrid, take a look:"
