After I got to the end I spent a lot of time looking for extra stuff to do in ALMOST the right place, so I eventually looked for tips on where to go online. I dont think the help is necessary since there are clues in the game. Maybe if I had just stopped playing and came back later with a fresh perspective I would have found it. Maybe.
Also, I had to look up the logic between the orange triangles.
And there is this ****ing puzzle that I solved through a mix and brute force and luck. I looked it up afterwards to verify that I had really understood how it worked. I had and still couldnt solve it. There are not a lot of bull**** puzzles in the game but this one is their king. Picture of the panel:
imo you should avoid looking things up online unless you are absolutely stuck. I lost interest in the game a bit when I did it.
