Great idea could really become a nice little strategy game with a few tweaks, it could use some tool tips for what the extractors/nukes do, and what kind of effects crashing into planets actually does. Very pretty as well.
Yes i didn't get to that part, but crashing into planet wipes all life back to single cell, nukes increase radiation (radiation increases temperature but damages life if too high), extractors give you income bud decrease value of asteroid and give you chance to find ancient artifact
