Hill Climb Racing wouldnt stand a chance if this went on Google Play. Imagine mining everytime you are travelling, bored etc. No need to sit by comp and spam f6. Getting this mobile would def bring more attention to the coin. I can bet on it.
What kind of controls do you suggest? You need 5 buttons for controlling the bike alone (gestures don't work, reaction needs to be instant), add at least rewind, restart and generate new. Plus full view if people use that. 9 buttons crammed on a touch screen and you'd still need to see the game.
