I took part in #PyWeek 39 over the weekend and made a game in #PyScript. It's a single-tap rhythm game. Should work on any desktop browser and most new phones. It was a fun challenge to make a game where the realtime music sync is so important. You want to let people tap a little too late and still have the game allow it. You want it to be playable with Bluetooth headphones and keyboards that add a lot of latency.
