And interesting and charming idea. I enjoyed the simplicity of the art, well done. I encountered a bug though that when you build a planet, then click a resource to collect it before dragging out the planet, it doesn't let you drag the planet out unless you add another resource to the planet, which did result in a game break when I had a four resource planet on deck.

Very charming game :) wish there were more variations by mixing elements together (and i somehow broke the game so i couldnt drag the planets out of the creator :/ )

Beautiful artwork but a bit sad that there's no web version (I don't really like downloading from here for a jam). Because of the coverart I decided to do it though and it did not dissapoint. The planet's continuous screaming when I picked up a planet did get on my nerves a bit though after a while.
