This Lighthouse of Madness walkthrough covers the game’s main systems on launch week. You play Dorian Cannon, a lighthouse engineer who explores Darenne Island, solves escape-room style puzzles and tries to keep his sanity from draining away. Sanity falls gradually over time and changes how the game plays, so work through each area without wasting minutes. However, the game is only a day old, and I could not verify the mirror beam solution, the mine door code or the endings, so this guide explains how to approach them instead of guessing answers.
Summary: Lighthouse of Madness walkthrough
- Release: October 21, 2026 on Steam, from Flying Jack Studios.

- Unverified: the mirror beam answer, the mine door code and the ending list.
- Content note: the store page warns of horror and substance abuse themes.
What Lighthouse of Madness Is
Flying Jack Studios made Lighthouse of Madness, a first-person psychological horror adventure with a Lovecraftian setting. The official site says it draws on H.P. Lovecraft’s The Colour Out of Space, and it describes you as a lighthouse keeper who repairs and installs autonomous systems in old lighthouses.
The story starts with a rescue. Dorian is sent to bring the keepers on Darenne Island back to the mainland, but the island sits near Innsmouth, and something is clearly wrong. The island has a towering lighthouse and a long-abandoned mine, and you explore both.
The Steam page lists the genre tags that matter for a walkthrough: puzzle, investigation, hidden object, exploration, linear and single-player. In other words, expect to examine objects, collect clues and use them somewhere else.

How the Sanity System Works
Sanity is the headline mechanic. The Steam page says it works like an escape room: your sanity gradually deteriorates over time, and that affects gameplay. The same page also says the game asks you to try not to lose your sanity.
Here is what that tells you:
- It is a clock. Sanity drops with time, so wandering slowly costs you.
- It changes gameplay. The effects get stronger as it falls.
- Story events can push it down. The marketing says it drops as you uncover the island’s darkest secrets.
The developers have not published a list of what restores sanity. Because of that, I cannot confirm the common ideas players suggest, such as standing in light or using certain items.
One old demo discussion adds a caution. A player reported that death worked like a sanity timer, that dying sent them back to the start, and that going insane led to a different world with a puzzle of its own. That post is from the demo era, so the full game may behave differently. Still, it hints at a sensible plan.
How to protect your sanity
These tips are general advice for a timed horror puzzler, not confirmed game mechanics:
- Plan before you search. Look at the room, then decide where clues likely sit.
- Pick up everything useful. Items often unlock puzzles elsewhere.
- Do not backtrack without a reason. Time costs sanity.
- Save when the game lets you. Check your save options early, since the demo sent players back to the start.
- Watch the screen. Visual effects may warn you before your sanity breaks.

Mirror Beam Puzzle: How to Approach It
I could not find a verified solution or even a description of this puzzle’s layout. So I will not give you mirror angles. What I can give you is a method that works for beam-and-mirror puzzles in general. These steps are my own advice and not confirmed details of this game.
- Find the source and the target. Work out where the light starts and where it must end.
- Look for obstructions. Anything in the beam’s path, such as debris or props, may need clearing.
- Identify what you can move. Turn each mirror and see which direction it sends the beam.
- Work backwards. Start at the target and trace the light back toward the source.
- Change one mirror at a time. That shows you what each one does.
- Check the clues in the room. Escape-room puzzles often hide hints on nearby walls, notes or objects.
If the puzzle uses filters or colored light, the same logic applies. Test each piece, and note what changes.
Abandoned Mine Door Code
I could not confirm the mine door code, and I could not confirm whether it stays the same for every player. That matters, because a code that a site lists for one playthrough may not work for yours if the game randomizes it.
Here is a safe way to handle any code puzzle:
- Find the clue first. Look for notes, journals, scribbles or labels that mention numbers, symbols or sequences.
- Write it down. Capture the code in the moment, in case the game changes the screen.
- Test small. Enter it exactly once, and watch what the lock does.
- Do not copy codes from other sites blindly. Check them against the clue in your own game.
The store page confirms the mine exists and that you explore it. It does not describe the door or its lock.
Story and Endings
The sources I found do not list the endings or the choices that lead to them. I will not name them, because any list would be invented. What the official material does say is that you uncover the truth about the missing keepers and the island’s dark past.
To find out how many endings exist, check these places after you finish:
- The Steam achievements list. Ending achievements usually show how many outcomes exist.
- The main menu. Some games add a chapter or ending screen after a run.
- Community guides. Players will map the endings within the first weeks.
Until then, avoid any site that lists exact ending names or triggers without showing screenshots.
Tips for Launch Week
- Play with the lights and sound on. Clues often live in both.
- Take screenshots of codes and notes. They save you from backtracking.
- Check the key bindings. Many indie horror games let you change them.
- Pace yourself. Sanity falls with time, so avoid long pauses in dangerous areas.
- Read patch notes. A day-one patch may change puzzles or sanity.
What Is Still Unconfirmed
| Topic | Status |
|---|---|
| Mirror beam solution | Not found |
| Mine door code | Not found, and randomization is unknown |
| What restores sanity | Not published |
| Story endings | Not published |
| Full puzzle walkthrough | Not available yet |
Common Mistakes
- Copying codes without checking. A code may differ in your game.
- Rushing past clues. Notes and objects often matter.
- Wasting sanity. Time drains it, so avoid aimless wandering.
- Trusting unverified ending lists. None exist yet.
- Skipping the demo notes. Early demo behavior hints at how death works.
Conclusion
Lighthouse of Madness is a short-timer horror puzzler, and the best walkthrough on launch day is one that teaches you how to solve each puzzle without handing out unverified answers. Protect your sanity by moving with purpose, approach beam and code puzzles with a method, and wait for community guides before you trust any ending list. Everything here is accurate as of October 22, 2026, and I will recheck the details as players finish the game.
