I wouldn't advise it, this was almost a week ago and if it was free for everyone we'd definitely know about it by now.
Don't wanna burst your bubble, but the update came out yesterday and you could've downloaded the update instead. :/
Yeah I know, I said earlier I can see both the game and the update, and both say free. The first one says v1.0.
Yeah, I think this was what happened. he downloaded the update and it stated it was 'Free' in the purchase history and he thought it was the original 1.0 version he bought for a buck.
But updates do show up in your purchase history in iTunes, which is what he checked. So no, I don't think he got it for free.
*Facepalm* Check back the thread again. He did get it for free. Now unless Midian is lying, he DID get it for free.
