Ufo-Planet Gates

In the game, there are 47 of the planets and satellites in the Solar System. You must move UFO by touching the screen.
When you start the game, you may think that the planet and its satellites are a barrier and you should not hit them. Unfortunately, this is not the case. You can not go under or over the planet and its satellites either, also when you touch the flames in the top and bottom strips, the game is over. The only way to pass is inside the planet and its satellites, however you must be very careful while you are passing through it. If you will pay a little bit attention and be careful, you will get very good scores. The game has been tested very well. That is why you are wrong in your opinion, if you think that there is a flaw in the game's system.
