The game is great but the mechanism gameplay is hard

The game is nice and great graphics but it is quite difficult, the gameplay is very nice.

So heard this was the hardest game so naturally i tried it. In my opinion its fairly easy but why the 2 stars? Cause two big reasons why this game can an will frustrate you and its not even cause of the game play. One main reason is the controls. Left     Right     Jump. Spaced apart yet simple right? But other than the fact unexpected things can pop out at at any turn, your thumbs are taking up most the screen to rarely see whats going on when traversing. A simple joysick and jump button would of been more practical but no. Its got to be a hard game so youre part of your own down fall. An 2ndly the Ads...the useless pointless Ads. Cause soon as you die ypu get a 5 second ad or a picture to skip immediately but the worst is the "continue?" Ad. Press it thinking you'll start off where you failed. Bzzzt!!! No! You get a 30 second ad  just to start off whereever the game once to put you farther back. Only difference is from tapping the play button is: you get the automatic 5 second ad, sent back to the title screen, hit play just to end up exactly where the 30 second ad would put you. So what makes this game hard is you not being able to see with your fingers all over the screen an then automatic Ads to push your frustration more. Game is a good idea but not worth much
