Robot Unicorn Attack is a sidescrolling platform game in which the user controls the movement of a robotic unicorn in a manner similar to Canabalt, a game released in 2009. The object of the game is to prolong gameplay without falling off the stage, crashing into the edges of platforms, or colliding with crystal stars (without first dashing). Points are earned with play time, by collecting pixies, and by destroying crystal stars by dashing through them. As the game progresses, the stage slides faster. Jumps and dashes can be chained together while the unicorn is airborne. The player has three lives (referred to as "wishes"), and the sum of the scores from each life count for the player's final score.
