Robot Unicorn Attack does one thing, but it does it very well. The unicorn runs and the player jumps. This is a tried and true formula that has worked over and over again. This has proven so successful that even massive gaming corporation, Nintendo, plans on using this gameplay mechanic on a new Mario game set to release on Iphone and IOS later this year. There really isn’t much to say about this simple yet effective killer of time. This is a game you just need to try for yourself. Head on over to the page, hit play, and start jumping. As a friendly tip, avoid the stars. If the unicorn touches a star he explodes and its decapitated head starts crying crystals.
