This is a follow on from the previous post in case you havn't already seen that.
Made some more changes to the planetary rings by removing the 3D effect which made them look like they went behind the planet. They now look flat and circular, which I think fits much better with the graphical style of the game.
This also means I can put small ice asteroids within the ring, which could possibly be used as a resource for something in the game.
I am going to create new graphics for the ice asteroids/chunks which will be a bit smaller than in the screenshots and look more like sharp ice. At the moment they are using the same graphics as the ore asteroids.
