ahahaahahaah you absolute maniac, i have never seen anyone putting a whole chess game as a minipuzzle anywhere. I love the full eerie and panic mode atmosphere. Hard puzzles do contribute to a nightmarish feeling. My only criticism is that maybeee you exagerated with them. Like sure, maybe you did it to keep away normies. But for example there is no way I could have solved the Knight's tour puzzle without writing a code to do so, it's way too random and excrutiatingly difficult to guess right 24 moves. The moving card one was fun. No idea how to solve the cross with bottles one, with "colours" as clue. I guess one must make every square the same colour? Also the puzzle with two squares one red, one gray confused me quite a bit. I managed to make the left square entirely red, but that's not the goal? No idea what to do there. Anyway I absolutely love and hate this game at the same time, but I am afraid I will never finish it. Too much trouble. If you had introduced some sort of growing difficulty thing to train the player a little bit, that would have been interesting
