All too often people underestimate the appeal of the double jump. A staple of many platformers of old, the double jump has fallen somewhat out of favor of late. It’s noticeably absent from single-button micro-games like Canabalt and The Impossible Game. So we’re pleased to see that Robot Unicorn Attack brings it back in a big way.

More noticeable, though, is that it brings back weirdness in a big way. We’re talking psychedelic mushroom-eating, acid-dropping weirdness. In other words, it’s an average product from Adult Swim, the network that hijacks the Cartoon Network every night starting at 10. Robot Unicorn Attack is a port of one of their popular Flash games, which you can play here for free.
