First things first. If youre expecting the same freestyle physics based game like the touch grind games, dont bother purchasing this. You ride around on closed circuits cluttered with dumb obstacles and invisible walls. It absolutely ruins the experience. The responsiveness on tricks is on the same as youd expect. The physics/mechanics behind navigating/landing is subpar. Tricking, challenges, and multipliers are standard. Bike customization is non-existent. Given the success of the touch grind series, this game is a disappointment. To a casual iPhone gamer, this was not a well spent $5
