It's made in the latest version, v0.99.72. Get it here: viewtopic.php?f=2&t=5363
Whenever I make an example .cap for somebody I'm just going to assume they have the latest version. It saves me time and energy wondering what version they might be using.
Anyway, the .cap is nothing special. You click on a sprite, it changes a global variable. Should be pretty self-explanatory.
Though my example does use a family for the three different sprites in order to cut down on the number of events.
