Check your journal. Also another hint is in computer notes. If you did not read the notes or simply forget about another cave, there is also a hint if you tried to open locked watchtower door. It will updated your journal with aditional info. You probably miss the second cave. In order to get the key you need to solve the red box puzzle.
Hope this will help you. Feel free to contact me on twitter or discord for further help.
I figured it out. The photos really throw people off because they don't first see the numbers of the one photo are of the side of the combination instead of the actual combination. That puzzle really does ruin the experience and immersion of the game. I ended up looking it up on youtube then just watched them play to the end since the immersion was already ruined for me. Puzzles like these ruin horror games these days. I highly suggest removing that puzzle or making the protagonist say "huh, if I line up those side numbers, I should get a good chunk of the combination" or something similar to clue in the player more so they also don't have to alt-tab out and break their immersion.
Do you mind message me on twitter/discord? I was getting only positive feedback on this specific puzzle so far so I can’t just remove it but I would like to discuss your difficulties with it and verify something. Maybe find more optimal solution most probably for asisted mode.
My goal is to make the puzzles challenging but not frustrating. So if someone struggles with the puzzle I would like to provide as much clues as possible but don’t ruin the puzzle experience at the same time.
