Hi, thank you for a great game.
I just thought I gotta tell you there's some ambiguity about the game's price. I think people who have a problem downloading it paid 1 dollar, not 3 dollars - because frankly, this page makes it look like the game costs 1 dollar.
My friend also paid a dollar and could not download it. I paid 3 dollars and I was able to download it. I'm not sure what your intended price for it was, but currently, it seems many people are mislead to believe it costs 1 dollar.
