I first played DCSS on 2018-11-01, when I installed version .22.
I was happy with the .23 update, but not with .24 and subsequent changes. So I still play .23
I'll publish all my DCSS notes in the public repo eventually, to show my learning curve.
I am a touch-typist who abhors lag, so I've never played online. Also, the online UI is inferior due to browser limitations.
