I love that you have a README and License file (main criteria for open source category). Add a screenshot or two to spice up your README even more.
Love this take on the theme. It's an addictive game with lovely sound effects and music. It was also fun holding down one arrow button to see the circle just spin around really fast! It'd be awesome to see a scoreboard or high score somewhere for tracking, chill game with lovely vibes though. Intuitive, simplistic, and fun. Great submission.
