Cool game but needs more objects

This is a super duper ultra fantastic game, but I have a favor: Could you add more planets? Plus, Why does it do this when a gas giant collides with a star? It doesn’t change its color and if you put a LOT in there, it shrinks when colliding with the other star? Suggestions: Ice Giants. Ice giants are blue/purple gas giants but freezing cold. When placed in the habitable zone, it’ll turn into a gas giant the exact same size. Craters. Craters are formed when a planet collides with another planet. Only applies to planets with land. Star Types. Star types are like M, K, G, F, A, B and O. They influence how hot they are. Bugs:I saw a lava planet hotter than a star. There is a chance that the sun’s light will flip, no names appear, all rotations stop and you can’t press any buttons.
More Suggestions: A planet rings option when you click the hammer in case people forgot the rings. Rockets. Rockets can fly in and on the target planet. There can be planets, moons and asteroids you can go to. Humans. Humans are little dots that migrate and wander around during Tribes,Industrial and Satelite eras of life. Planet Maker. A planet maker is where you can draw, use shapes and build hitboxes!
