Lap Uranus dumps you into a suicide mission. You are the pilot of an out-of-control rocket that only has one working control remaining, the “Turn Left” button. Touching the screen activates a burst of your “Turn Left” rocket; touch it too much and you’ll be ploughing into Uranus at high speed, don’t touch it enough and you’ll be sucked off into outer space.
The rings of Uranus are your only haven. Stay in there for long enough and pray that someone comes to rescue you.
