Your comment is marked as [dead] (and so is the other one that mentions GPT-5.1 and the other stuff) but I can read it but cannot write a response directly. I am unable to access that URL. I know what you meant that it is Sokoban inspired (and I did not intend to disagree with that or to dispute that); what I meant by my comment is being a similar class of games even if it is not Sokoban; I don't know what such a class of games would be called ("Sokoban" might be misleading even if it is not entirely wrong).

Do you have a document explaining all of the rules? (I think it is unfortunate that too many games do not make the rules clear by writing long documents about their working. How should you know how to do it if you do not know its working?)

(I had made a puzzle game engine that does not require a web browser nor an internet connection, and has no spyware or analytics or telemetry or anything else like that. Some puzzles can be made by it including stuff similar to sokoban.)

I reached a point where the levels became trivial. Before that most were a bit unsatisfying because the difficulty was in ignoring irrelevant things rather than finding a clever route.
