Please check out our game, the developer of Jack Lumber asked me, as I walked through the indie booth.
My reply, because I was in a hurry: Can you pitch me the game in 10 seconds?
In fewer than 10 seconds, the developer told me that the game is about a man whose grandmother was murdered by a tree. It's a revenge story.
Sold, but I'd have to come back the next day.
We came back and he started playing. It... looked like a Fruit Ninja clone. And then it got interesting. Very interesting.
Bottom line: I really am sold. I think Jack Lumber (official site here) is a winner.
