I enjoyed both Monument Valley 1 & 2. Any other good mobile games like this?
Not so much Monument Valley-like, but I also found The Room tetralogy (quadrilogy?) very enjoyable. Certainly a very different aesthetic from Monument Valley's whimsical colour-palette and story line, but excellent puzzles nevertheless.
There are five the room games, not four.
The VR game isn't "mobile-only" as per the parent post
