Robot Unicorn Attack - Jump into the steel hooves of a robot unicorn, prancing freely amongst the lush purple grasses and rainbow-strewn. Collect butterfly fairies as you go, leaping majestically from platform to platform and dashing through the glass stars that block your path. You have but three tries to realize your dreams of a high score. Use them wisely. Robot Unicorn Attack is played with the keyboard. Z – Jump. X – Dash. You can jump again in mid-air by pressing the Z button again.
