Started it last night with my wife. We solved about 30-40 puzzles, all very basic at this point.
I didn’t know the best place to go(like, where to go that would lead me in the natural path to learn what I need). We went through the canyon to a building that opened with a symetrical puzzle(two lines form instead of one). I solved a panel in the back and came back out to solve the wall that got charged with that one.
Also, as we exited the introductory castle-like building, I turned left and solved a green door. I touched all the black hexagons to solve it(uh, sorry for the massively easy spoiler there).
I also found a very light grey(or white) panel inside on the floor. It had a little triangle in the lower right corner and I was able to solve it, but not understand it. I solved it wrong several times as well(in order to learn), but I have yet to understand what creates the correct solution.
I don’t need any help at this point; I’m just sharing my thoughts. Very neat.
