The No Man's Sky of cubic planets (no 100% all), It has a fantastic abstract and minimalist universe, there are even small planets and asteroids that orbit around black holes. The controls of the WebGL version are the ones that leave something to be desired.
Alas, Webgl has many limitations and much lower performance than standalone programs. Try the standalone version.
Planets and moons have gravity, which causes the player to fall into the center of the planet and somewhat holds back the player in control. Therefore, you need to use the mineral "Antigravity."
And also, I conducted some experiments with the player’s controls, perhaps they are not very successful.
