... seriously? The game pretty much flashes ads every minute (when you win the level, when you lose, when you go back to the home screen, anytime) however you can’t even pay for the no ads version because that feature does not work. Also, there not a retry button - if you started off bad, sorry, need to wait a whole minute for the level to end. Difficulty is not well tuned either, in many levels even if you get all diamond and large gold rocks you still finish with 1-star. If you want full score in some levels, the only way is getting lucky enough to get the right power-up before the level (after, of course, watching another ad). Btw, how come there are no achievements? The game itself is enjoyable but everything surrounding it was, unfortunately, very poorly designed. 1 star.
