Current version is bugged.
I doubt this problem is universal, but it will effect a lot of devices considering I am on an ipad 2. Basically, the game is marvellous and beautiful except is crashes frequently and the last level always crashes. The game itself is only able to auto-save every time the dungeon is finished, and more often than not, the loading screen after you finish the dungeon will cause a crash. The game is amazing but if you are buying, be prepared for a frustrating experience.
