It's basically a horror ebook application called Jed the Caver that my friend and I made. He did all the programming, I did the graphic design (aside from the title screen), and tightened up the story considerably.
It's fairly creepy and a fun read, so if you want a free promo code, just shoot me a PM. I have about 15 codes I can give away.
Apparently this only works on iPhones located in the US, so fellow Canadians are out of luck. I have no idea how all that works since I don't deal with the actual store on my end!
Here's the link to the app site if you want to see the stunning three lines I wrote to promote it!
