Decent enough roguelike until you reach a pay wall where you have to watch ~20 ads per island (and one before each run!) or pay SEVEN DOLLARS --more than many full premium games with hours of content-- for just three additional islands. The price is frankly unjustifiable. I'm happy to support developers of a game i enjoy, but most games would charge 1-3 dollars for the same thing. I would suggest the developers look to the monetization models of other roguelikes on the app store and rethink.
