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.
If the review is about a casual web game and if instead of reading quotes, your impression and your ads I can experience the game myself then yes we should point to the product.
