[PC or console?][before 2016, likely 2010's] 3D Puzzle game with some sort of non-english (I think French) title.

The setting was on top of a table and I think you were tiny and walked around on top of the table

I recall there being classic table top board game/ children's toy pieces (like checker boards, chess pieces, toy wooden blocks, maybe a classic nutcracker statue?), with them making up the level design as they are all large from your perspective.

the graphics weren't stylized, and the game was set in a 3D world.

The game's aesthetics reminded me of Superliminal, but I'm sure it isn't Superliminal.

I saw the game briefly on a youtube video recommending puzzle games during 2016 (unfortunately couldn't find the video in my history)

I think the gameplay involved exploring the environment and completing mind-bending puzzles that interacted with the environment (either the puzzles involved some sort of optical illusion or non-euclidean geometry stuff, or the puzzle was integrated into the physical environment like some of the puzzles in "The Witness"

Honestly I'm not super confident on how reliable my memory is about this game.
