You are the only quadrilateral on Quadra affected by gravity. You are also the only rectangle. The squares hate you because you're different, and they want to hurt you. You should avoid them.
Tap anywhere on the screen to jump and use your exemplary maneuvering skills to avoid the red squares for as long as you can (oh and watch out for the purple squares too...).
As frustrating and addicting as this can be, you'll also find yourself getting into a groove and relaxing to the chilled out music with a futuristic vibe.
Good luck!
