Archaica: The Path of Light
I highly recommend Archaica for fans of puzzle games.
The puzzles comprise minimal ray-and-grid mechanics but often combine them in clever and surprising iterations. They start easy but quickly become challenging. There are a lot of them and they are all satisfying. Some are truly delightful! I spent close to an hour on just one puzzle until figuring it out and marveling at the solution.
There are pleasant hidden-object bonuses in most levels. These are not absolutely required but they do give an opportunity to explore the gorgeous and diverse 3D environments.
The game description mentions an "intriguing narrative" but that's overstated. The story provides superficial background and nothing more. This is a pure puzzle game with no "adventure" elements. And that's fine.
