Rainbow Dash Attack is a parody of the widely popular side-scrolling Robot Unicorn Attack. Instead of a robot unicorn, you play as Rainbow Dash. The music featured in this game is Always by Erasure.

No gameplay has been changed from the original Robot Unicorn Attack Game, and only a few other things have been reskinned. The game has no story, the only goal being to jump over cliffs, and not run into solid objects in order to make your points reach the highest they can. Collecting the butterfly things will give you point bonuses, along with Dashing into the giant stars.
