This game is the standard for how all endless runners should be compared. Actual levels as well as endless modes give players a sense of accomplishment or the quick fix you could be looking for at the time. The upgrade system gives the player a reason to keep coming back as opposed to just trying to beat your high score.
As for the gameplay, the game is fast paced and addictive. Giving the player more controls than simply timing your jumps adds to the intensity. Think Mirrors Edge on speed.
