This is Project Monolith, a first-person puzzle game with one hell of an art style.
Going all monochrome is a bold choice, especially given the perspective, but it works really well here, as it's not only tying into the design of the world, but giving the game a trademark look at the same time.
It's been worked on quietly for two years now by a small team, and will hopefully be out next year on PC.
