I took part in 39 over the weekend and made a game in . 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.

The logo screen of the game. STREAMLINE is written in the middle. A single three-dimensional multisegment line spans into the horizon in the background. The aesthetic vaguely resembles the "cyberspace" from TRON or Hackers, with blue-ish green-ish colors dominating.
