This is a game for physics lovers and history lovers. Its UI menu interface reflected its own scientific attributes: planets moving on the curvature of space-time caused by gravitational fields.
Then you can choose a star/planet, such as the Moon or the Mars, for a landing-on adventure on an expedition rover, or you can navigate the space from the perspective of a spacecraft.
But if you think this game is just such a space simulator, then you underestimate it. The aforementioned contents are only 5% of the game.
In fact, this game has very rich time and space travel and space exploration functions, and it has great fun:
You can drive a spaceship, explore different kinds of extraterrestrial planets, and in a far away galaxy called Magda Nebula, you will fight the alien fleet and experience the space battle described in the 'Independence Day' movie.
You can command a submarine, to explore the underwater world, and to seek for the lost Atlantis.
You can also build your own world, in the center of the earth, like many Minecraft-like voxel games, you will create a paradise of Verne fantasy.
You can also decrypt the secrets of the Relativity, and observe the world seen by a traveler riding a photon by flying at 90% speed of light.
You can also travel through wormholes, and come to some lost historical periods: Ancient Rome, Ancient Egypt, Medieval Dark Ages, etc., and to defend their civilization with your fighting system.
It is not a prefect game yet, but this is our endeavor to introduce real physics into games.
