Managed to spend a few minutes with the game tonight and I can't add much more than what's already been said. The game is incredibly atmospheric and the art is painfully beautiful. Looking forward to spending more time with it.
I really enjoyed this. Definitely the most interesting and polished point & click adventure in quite some time.
Just saw that this is free today with no mention of iap in AppStore description. For any still on the shelf about this, you really owe it to yourself to give this great atmospheric adventure a try!
