If anything I'd say Fez's real achievement is the art. Once the novelty of the 2D/3D hybrid gimmick has dried up (which happens pretty fast), the gameplay is pretty mediocre.

If you watched Indie Game: The Movie, it seemed like pretty much the entirety of Phil Fish's effort went into obsessing over the art. And I have to give him credit that it looks pretty damn good.

Dead Cells, HLD, both have much better art styles than Fez. Fez’s worlds were great but the choice of 16px vs 32px limited it in details, hence geometry carving of the 3D world to add more detail impossible to achieve with pixel art tiled textures without overdraw.

I’m not saying I disliked Fez, but to compare the art of Fez to Chronotrigger is like holding a child’s finger painting to a Van Gogh. From a distance they may look the same…
