That isn't what gamified means, and one should not be using such a term without knowing what it means. When in doubt, stick to simpler descriptions. Hence calling it poorly editorialized.
To me, gamelike user interface would be simply editorialized, while gamified user interface would be poorly editoralized. One is editoralized with an opinion, the other also has an error. It isn't a fact that it's gamelike over all, nor is it how it's described in the README - the author says "with a game inspired menu system" which is a far cry from game-esque, game-like, game-ified, etc.
