Wow, this is amazing! Great pixel art, great music. And a nice pseudo 3d effect. I don't use GameMaker, but I imagine that it would have been challenging to implement.
Thanks man! at first I thought it'd be hard to make the effect, but turns out all you have to do is make the planets closer to the center move outwards more slowly than the ones far from the center, all of the Z coordinates increase at the same rate. -Grey
