In the game Orbit Challenge, you and I will get into the world of small particles called atoms. You will need to hold your atom to merge with another microparticle. You will see on the screen a nucleus around which small particles run along the orbits. You will have to click on the screen to send your character to flight. He will fly to the orbit and will move in a circle. Your task is not to allow a collision with another object. So, look carefully at the screen and send your hero further. The level is considered passed when you reach the center in which the core is located.
