Roll & Run

Don't be fooled by the simple structures and colors of this game, the physics of it all will get you. Try out the first level filled with dominos, ramps, and more, but watch out as you progress. As you pass levels the speed of the ball increases while the obstacles become thinner, longer, and more recurrent—ultimately just harder. Although easy to conceptualize, playing the game requires calculation and agility at some points and nothing but speed at others. It's hard, but beatable.
