There is a misunderstanding about Robin Johnson's entry in ParserComp 2021. He entered the game "Gruesome" (probably made with GrueScript?). However, in that game the parser was not disabled. I would say it was a traditional parser game with a twist (the twist was about dark/light locations). You can play the game to see that the game is a parser game though you first have to push the start-button.
