Like every six year old girl in the 1980's, I had this picture or something similar to it in my bedroom. My folders had unicorns and kitties. My sticker collection was 50% cats, and 45% unicorns, and 5% Hot Wheels.
Obviously I would have loved Robot Unicorn Attack as a child.
Robot Unicorn Attack is a straight forward flash game. You jump on platforms, collect fairies, dash through stars, and try not to crash or fall to your death.
The beauty is in the details. There are rainbows EVERYWHERE. You explode into robot parts when you die. Your fairies are made of rainbows. Pink dolphins appear as you build up speed. You are a robot made of unicorns and rainbows. Rainbows! And the most relaxing song ever written plays in an endless loop.
Tangentially related, it inspired one of the best/worst/most unplayable maps in Team Fortress 2.
Rainbows and koth_always make scout cry
