I may have missed this in the article, but I am wondering how much this game sells for. I am not familiar with the pricing of indie games on xbox live.
Congrats btw for releasing your game! Very interesting article!
Edit: Ok I poked around a bit and found that the game is listed for 80 Microsoft Points. On my account it is $14.50 (not sure if this is Canadian or USD as my account is Canadian) for 1000 points, making the game cost about $1.16.
