It's great! Bought it on PC  it runs better there. Anyone complaining about the lack of saving  you have to pick up an orb of safety and it'll reset the world but not progress or type of land you're in. After that  when it's still active for seven or so turns  you can save and quit and kill the app. That orb is in the Land of Eternal Motion and saving is it's sole purpose.
