I first tried the freemium version on Air 1 using 7.1.2. It was way too frustrating as the screen did not register taps, and I almost ruined my index finger. I then tried that version on Air 2 using 8.1.2. It seemed to work, and I bought this, a mistake.
..I have now downloaded it 3 times, reset Air 2 each time, I play in Airplane mode with all other apps turned off. Keep in mind these are very long levels, and it does not save your progress. Walkthroughs stating level times are for people using a mouse with the ability to click items with precision. Times are much longer using a stylus or finger when you have to tap over and over again. If things like pots and gold are close together, you often un-tap one and have to do it over.
..On the second level, the much needed gold is almost impossible to reach as it is in the lower left corner next to the giant head. You cannot progress without this. Realore does not update their games. I love their games and own around 10. This is the worst because when (not if) you crash, you have to restart a very long level. Too bad as it is a very long (really long with crashing) and interesting game.
