All But Me
You are all by yourself, in the middle of a vacuum, sprinkled with the occasional planet, asteroid, sun.
You can meditate while riding the gravitational swings of planets, or you can try to upgrade your ship with a modest repertoire of tools.
Using the tail of your ship, you can create hypnotic dances around planets and their gravitational pull.
iPhone 6, 6S, 6+ and 6S+ are supported.
