Very neat. I liked the particle effects. Sometimes when I made something I couldn't find it later. Something I'd like to see is a way to locate what I've made. 

The game is very nice :D, I don't know much about Godot, but it seems like a technical feat to make the planets and particles that way in this engine (I understand that it doesn't have very good support for 3D), I really liked it, I hope they continue updating it, for example adding collisions in the planes
