The flying saucer has been flying for many months in search of planets where at least some life is glimmering. Until now, the flight was calm and even a little boring in empty cold space, but suddenly some strange buildings appeared right in the void. The crew members were a little surprised and decided to explore them, and you can help them with this in Flappy UFO. The barriers are located opposite each other at different heights. Between them there is a free gap through which you can carefully guide the ship so as not to hit either from above or from below. The task is to fly the maximum distance in Flappy UFO.
