Cratergut terms of use
Cratergut is licensed to you, not sold, under Apple's standard End User Licence Agreement for applications.
Buying things
Cratergut sells one thing: a purchase that removes the adverts. It is tied to your Apple Account and can be restored on any device signed in to that account, from Settings inside the game. Refunds are handled by Apple, not by us.
It removes all of them, not only the ones that interrupt you. The optional advert you can choose to watch in exchange for a hat goes with them.
Playing with other people
Online play uses Apple's Game Center. Behave decently toward the people you are matched with. Trying to interfere with someone else's game, or with the game itself, may mean losing access to online play.
What we do not promise
Cratergut is provided as it is. It should work, we test it, and we will fix what we can, but we cannot promise it will never fail or that online play will always find you an opponent.
