Very cool, thank you for submitting! I had a lot of difficulty understanding how my changes would effect the outcome, and it seemed I had to use trial and error at all times. The visuals are beautiful, but the collision sound is terrible haha, I hated losing exclusively for that reason. With the sound off, adjusting the planets and sending them off was a lot more pleasant. Also, consider changing the swap button from Tab to something a little easier to hit in standard WASD formation, like Spacebar or E.
Overall, very nice submission! Hope you had fun, good luck!
