Lovely art, and such a sweet, playful idea: blowing out the torch for the Earth's birthday made me smile. I didn't hear any music or sound on my Mac in Chrome, so I wasn't sure if there was audio or if it just didn't start for me. A little birthday tune would be a perfect touch! Happy birthday, Earth!
I made AI WORMS for the jam too, a one-button whack-a-mole: https://seymour8glass.itch.io/ai-worms. I'd love your honest rating if you get a minute.
