It all started when Ryan Henson Creighton, awesome dad and game developer, decided to take his daughter Cassie to the TOJam game jam in Toronto, Canada. With his daughter he created Sissy’s Magical Ponycorn Adventure, a free to play Flash game with art, voices, and design done entirely by five year old Cassie. Since then it has become somewhat of a worldwide sensation, and through donations Ryan has raised nearly $3,000 to put towards Cassie’s education. The game is good, too. It’s probably the craziest point and click adventure game I’ve ever played through, and it’s basically impossible for the story of its creation (and success) to be any more heartwarming.

Sissy’s Magical Ponycorn Adventure [$2.99] was just released for the iPad on the App Store, further expanding the Cassie’s Ponycorn empire. Check out the trailer below to see what it’s all about:

The game itself is short, and really, you can play it in its entirety for free online if you want… Or if you’ve got an iPad you can grab it on the App Store to pitch an additional $3 to Cassie’s education fund.
