So instead, just randomly place the three shapes until the game visibly "locks" them in to the "correct" place, which will be similar to this screenshot, but with the candle nudged left. To be fair, the cross/arches hint is clear to me, but that "drop" sure does look like a candle to me, and it's location relative to the rest comes with no hint that I see. Steam Achievement: "The cleansing Clear Blackwood from its demons."

--Fly back to punchcard bedroom. Notice wheel on bookshelf. Take wheel. Fly it to and use on barrel organ.
--Solve barrel organ puzzle. Suggested solution: you easily memorized that short little tune and delight in the musical adventure with no help. Author's preferred solution:Swear heavily for several minutes. Note that many of those punchcards sound SUPER similar.

--Go up to the next level. Seth follows.
--Codex: Misleading drawings
--Solve misleading puzzle. Mild hint:You can click on the underlined words. Moderate hint: Some people say that the underlined words match up to the nearby picture. Solution: Except the middle picture, which makes no sense at all. The solution is Curiosity, Righteousness, Ambition.
--Fly to top of tower. Take photo. Steam Achievement: "Blackwood reunited Gather Annie's sons four objects."

--Enter the new passageway right now and proceed to the end to get the bad ending. It's fine if you do. The game claims that you can't go back, but it's lying. If you click continue after the credits roll, you go right back to this point. Steam Achievement: "The fall of Blackwood Finish the game without fixing Annie's sons objects."

[lake.kubilius]

Kairibee, yes. I remember I posted a way to sort of "hack" a save file to get around this problem in the message board for this game. I assume the post is still there and that the method still works.

[Liger]

Can confirm hook in tower bug is still there, October 2024. Has there ever been a way around it discovered or do I have to restart?

[Casio]

Appreciate the answer, Lake.
I've checked and I had this puzzle done. I restarted the game and followed the entire first part of your guide by the book, but still didn't get the achievement. Perhaps I'll play through the entirety of it all following your guide some time, but not so soon.

[lake.kubilius]

Glad it was helpful, Casio! It's been quite a while since I played, but one from very early in the game jumps to mind as a likely suspect:
--Complete the puzzle in the fireplace in the manor kitchen. Make sure that the game clearly indicates it as done. (Journal will flash). (Paper Chase Part One.)

[Casio]

First of all: Thanks for this guide. That game had some good puzzles, but also some unfairly hard ones.
There's just one thing that bugs me. I completed the game, but I somehow managed to miss the achievement "Curiosity: Solve every puzzle in the game." Does somebody have an idea which puzzles could have been missable? I did not follow the guide all the time, of course.

[HornyPug]

4th time completing the game. 1st time completed it myself(fuck the music puzzles), 2nd and 3rd followed this guide, last time followed {COLLEGAMENTO RIMOSSO}walkthroughking.com guide. Esc menu shows 100% completion. I follow the guide to a tee, but I don't get the achievements.

[spykitty920]

Thank you so much for making this. Was my third time playing and determined to get my last two achievements. Thank you for making it possible!

[Kayzo]

I hate musical puzzles lol. Thamks for the help!

[lake.kubilius]

Glad it's been helpful jeb14!

[IHazDizzy]

Thank you for this! I was determined to complete the game without help but I missed the clue in Silver Labyrinth where I failed to see part of the piano keys clue before rotating the bunker photo (and clue looks only available before rotation as far as I can see). Infuriates me that the game is cruel like this...yet I'm still loving it
