Thanks for the feedback! As for the hint on the walls: J and I do not refer to specific walls; they hint (sorry for the repetition) at a skill you can use in the overworld
You should now be able to find the complete walkthrough on the game page 👍 There might be some differences in the layout of the maze (if I remember correctly, the early demo had less doors), but the puzzles and their solutions are still the same.
