[hardBSDk]

This issue explain how to implement this game.

• Add a 2D scene with black background
• Add a white circle sprite
• Fix the camera on the sprite
• Make this sprite push other sprites (more sprite size increase the gravity force)
• Add an orbit system
• Each new orbit will be far from the previous orbit
• Add a 50% of probability to make a orbit when the sprite come closer
• When some sprite hit the main sprite, increase the main sprite size
• Add sprite types for asteroid, planet, star, neutron star and black hole
• Make the player start with a asteroid sprite
• Add the asteroid sprite with a grey color
• Add the planet sprite with a random color (except black)
• Add the star sprite with a yellow color
• Add the neutron star sprite with purple color
• Increase the asteroid sprite size when other asteroid hit
• Increase the planet sprite size if some orbit is absorbed
• Convert the planet sprite to star sprite after some size
• Limit the star to make orbits with planets only, while asteroids can make orbits with the orbiting planets
• After some size, planets start to spawn spaceships, make the spaceships fly through the solar system and protect it
• Add the bloom shader on the star and neutron star sprite
• Make asteroids and planets draw shadows when some star pass close to them
• Make asteroids draw an eclipse on their father planet
• Spawn asteroids, planets with random sizes, stars and solar systems
• Add the black hole sprite with a black color, it don't move or draw shadows
• Add a cloud around the black hole sprite
• Add a way to lock anything that come close to a black hole and shrink its mass until destruction
• Add an orange color to the black hole cloud if some celestial body is locked
