来自火星的邀请：Here‘s a new 3D game appered. Controll your spaceship avoiding meteoric stones.

In 2020, the earth was no longer able to live for human beings because of environmental pollution. There was a spaceship bound for Mars for a survey. Six month later, when it was about to come at Mars, the spaceship lost communication with mission controllers on earth. After a while, meteoric stones which could not be found on the rader appeared around the spaceship, and geometric rings broke out.
Strangely, a voice from mission controllers can be read as you approach the rings.

"Pass through all the rings, and the system will start to work."

It was really like a voice from mission controllers, but you‘d never heard anything about this before the departure.
You obeyed the voice anyway and tried to get close to rings floating in space...
