Possibly relevant is hugi-compo round 3, the "Pong" compo: https://www.hugi.scene.org/compo/compoold.htm#compo3

I spent three days disassembling Guillermo Sais's 142-byte winner, which was challenging to understand. My notes may be of interest; they are in gsais-pong.md in http://canonical.org/~kragen/sw/pavnotes2.git/

I hope this is not interpreted as any kind of criticism. I would much rather be responsible for maintaining Joshi's code than Sais's. But I suspect that most people who are interested in either work will be interested in the other.
