A great concept and fun tools to go with it. There's the amazing background music ramping-up which is extremely fun, I want to learn how to do that! The art is pretty and has a correct amount of detail. The powers are fun and whimsical enough, and the lore to back them up (especially the "noxious gases") is logical.
Things I think may use some improvement: the character controller. I'm assuming this game is inspired from LIADS. If not, you should check out their character controller and gameplay. It could be incredible helpful. The main issues I had with it was that often, I was not actually in control of Earth, and would ram into other rocks or planets even if I react to them well. The feedback on gameplay was also a little incoherent. I couldn't really tell when the other ships would come, and then within 15 seconds I'd be surrounded. It was like I was getting SWATTED haha. I think some idea that there are rocks approaching, or a bunch of enemy planets, or whether there's cash-money-moolah ahead, would all help a lot.
Final words: I am a fan of LIADS, this was extremely fun for me. I hope you can make a post-jam version with some polish and mechanical balance. Cheers!
