Saving is extremely unclear, and if the app crashes you can lose a large amount of progress. Guess what! It crashes a lot. Combat is also extremely slow - it can take up to a minute between winning and being able to continue. Also, the skill trees are unfinished - all skills have the same description.
This is basically a glorified flash game at this point. Better games are available for less or for free.
