Pell Puzzles Review

I'd update the HN submission url to the actual source, i.e. either the above game url, or its "how to play" section at https://pell.achromath.com/how-to-play .
Currently the submission points to a third party review of the game - IMO it seems more appropriate as a comment.
Note that the whole review seems off topic too. It’s neither more interesting nor more accessible than the topic itself.
I can't see how are these off topic?
I have a few ideas for feature requests, but I'm not going to bother submitting them if it appears there's no interest.
