This app is too glitchy. When I tapped to play again, it closed on me instead. This was after I wiped out tapping jump over a cliff with no obstacles but was immediately sucked into the face of the cliff. This is inexcusable for such a well-established app and unforgivable. Casual games should just work on Android. It's not like this is Microsoft Office or Call of Duty, both of which should also work very well. It's not worth watching the ads only to suffer bad gameplay and design.
