I love the environmental simulation and deep secrets in Noita but it's not quite like Riven. Riven had me filling out pages and pages of a journal with notes and drawings. Many of these notes and drawings were my observations ended up being extraneous details about the visual design and lore of the world, because in Riven it can be very difficult to parse what is and is not relevant to progressing in the game. It's a very unique experience, I love a lot of puzzle games with secrets and meta layers, and I love Outer Wild's knowledge based metroidvania design, but no other game has had me scouring and mulling on every detail of this virtual world like Riven.
