Do you recall when I told you about KindleQuest, a website that runs adventure games like Zork for your Kindle? Amazon just released an app that removes the need for an internet connection.
It's called Dusk World, and after playing with it for a few minutes I'd say it's closer to the old Choose-your-own-Adventure books than it is to Zork. The price is $5.99, and it only works on a Kindle (not the apps).
Here's what Amazon had to say:
Dusk World is an interactive story for Kindle devices that combines interactivity with a graphic novel. The story takes place in Dusk City and combines crime, mystery, superhero and classic noir elements to create a vivid landscape full of colorful characters for you to interact with. The choices you make as Agent Patriot will lead you down different paths that determine the fate of both Dusk City and the world, not to mention Agent Patriot himself.

"I've been into reading ebooks since forever, but I only got my first ereader in July 2007. Everything quickly spiraled out of control from there. Before I started this blog in January 2010 I covered ebooks, ebook readers, and digital publishing for about 2 years as a part of MobileRead Forums. It's a great community, and being a member is a joy. But I thought I could make something out of how I covered the news for MobileRead, so I started this blog."
