Details

You own Mr Roller who never stops rolling. Tap anywhere when Mr Roller faces towards the coins and Roller will swing himself. That's the only way to move him. Catch as many coins as possible without hitting the obstacles.

Caution:
Never go completely off the screen. You may die.
Never hit the obstacles. You will die.
The more you tap, the faster Mr Roller will be rolling. So keep your number of taps to a minimum.

Powerups:
Tapping obviously costs you fuel. So catch two or more coins in a single sweep to get bonus points and hearts.
Use the hearts to continue the game when you die.

Sounds easy? Give it a try then.
