Weekend Lecture: Juice It or Lose It


Got 15 minutes to spare? Watch Martin Jonasson and Petri Purho explain how to use the concept of "juiciness" to turn a boring old Breakout clone into something way more exciting.

Watch the Video

Martin Jonasson runs Grapefrukt, where he posts a selection of his games, webbfarbror, where you can contact him to do work on commission, and prototyprally, a blog about rapid prototyping games using Flash.

Petri Purho created Crayon Physics Deluxe, and runs the blog Kloonigames, where he keeps an archive of games, each of which he made within seven days.

The term "juice" was coined in How to Prototype a Game in Under 7 Days:

“Juice” was our wet little term for constant and bountiful user feedback. A juicy game element will bounce and wiggle and squirt and make a little noise when you touch it. A juicy game feels alive and responds to everything you do – tons of cascading action and response for minimal user input. It makes the player feel powerful and in control of the world, and it coaches them through the rules of the game by constantly letting them know on a per-interaction basis how they are doing.

You can play the game itself here, but I recommend you watch the video first. The source is available on GitHub.
