I’ve spent the last three days staring at floor plans. Not for a kitchen remodel or a new apartment, but for a place called Mt. Dunwick. If you haven't heard of Blue Prince, it’s basically what happens when you take a classic "Inner Sanctum" mystery vibe and smash it into a roguelike architectural puzzle. It is weird. It is frustrating. Honestly, it’s one of the most brilliant things I’ve played in years.
You play as Simon Wright. He’s an architect who just inherited a massive, shifting estate. The catch? You have to find the elusive Room 46. If you find it, you keep the inheritance. If you don’t, well, the house basically eats your progress and you start over the next day. This isn't your standard point-and-click adventure where you just find a key and open a door. In Blue Prince, you literally build the house as you walk through it.

Every time you step through a door, you get to choose what the next room is from a hand of cards. Maybe you pick a Library. Maybe a Kitchen. But you have a budget. If you run out of "Stamina," you're done for the day. It’s a game about draftsmanship, greed, and a very creepy mystery that feels like a 1920s radio drama updated for 2026.
The Inner Sanctum Logic of Mt. Dunwick
The game feels like a love letter to the old Inner Sanctum mysteries. There's this pervasive sense of dread, but it’s not a horror game. It’s an intellectual dread. You’re constantly worried that you’ve misplaced a room or blocked off a vital hallway.
The developer, Dogwood Gaming, did something really smart here. They realized that the scariest thing isn't a monster jump-scaring you; it’s the realization that you’ve trapped yourself in a dead-end of your own making. You are the architect of your own failure.
Most people expect a mystery game to have a set map. Blue Prince says no to that. Because you are choosing the rooms, no two "runs" or days in the house are ever the same. You might find a clue in the Solarium on Tuesday that you can't use until you draft a Laboratory on Wednesday. It’s non-linear in a way that feels genuinely fresh.
Why the drafting mechanic changes everything
When you stand at a threshold, you’re presented with three room options. Each room has different attributes. Some give you items. Some give you "Key Fragments." Some are just empty hallways that cost you precious energy to cross.
It's a balancing act. You need to reach the center of the house, but you also need to find the tools to unlock the secrets hidden in the walls. I spent forty minutes yesterday just trying to figure out how to place a Gallery so that it connected to both a Study and a Bathroom. Why? Because I needed the water pressure from the bathroom to trigger a puzzle in the gallery.
The complexity is staggering. It’s not just about what the room is, but where it goes. You have to think three steps ahead. If I put the Greenhouse here, do I have enough space to put the Observatory next to it later? If I box myself into a corner, my day ends, and I lose all the items I gathered.
The Mystery of Room 46
The "Blue Prince" himself is a bit of an enigma. Without spoiling the narrative beats, the story is told through environmental cues and the occasional cryptic phone call or note. It’s very "show, don't tell."

You’re trying to find Room 46. That’s the goal. But as you dig deeper into the history of the Wright family, you realize that the house is a physical manifestation of a very messy, very wealthy family's secrets. There are hints of alchemy, weird science, and 19th-century occultism.
One of the best details is the "Blue Prince" statue. You’ll see it popping up in different rooms. Is it watching you? Probably. Does it move? I’m still not sure, but I could swear it was facing the door when I left the Dining Room, and it was facing the window when I came back.
The puzzles aren't just "find the key"
Let’s talk about the puzzles. They are hard. Like, "get a physical notebook and a pen" hard.
In one section, I had to solve a cipher based on the lunar cycle which was hinted at in three different books scattered across three different rooms. Because the house layout changes, those books aren't always in the same place. You have to remember what you saw and where you saw it, even if that room doesn't exist in your current layout.
- You’ll find ciphers that require real-world logic.
- There are mechanical puzzles that feel like a high-stakes version of The Room.
- The game rewards players who actually pay attention to the architectural style of the rooms.
It's refreshing. So many modern games hold your hand. They give you a glowing waypoint and a quest log that tells you exactly what to do. Blue Prince just gives you a drafting table and says, "Good luck, don't die."
How to actually survive a day in Blue Prince
If you’re just starting out, you’re going to fail. A lot. The first few days are just about learning the rhythm of the house.
The most important thing to manage is your Stamina. Every door you open, every room you place, costs you. If you spend all your energy exploring the basement, you won't have enough left to reach the goal. It’s a resource management game disguised as a mystery.
Don't ignore the items. You’ll find things like flashlights, lockpicks, and even blueprints. Use them. Don't hoard them. I lost a perfect run because I was trying to save a master key for "later." There is no later in this house. There is only now.
Understanding the "Void"
If you make a mistake in your floor plan, you create a Void. This is basically a dead space where no rooms can be placed. Voids are run-killers.
I’ve found that the best way to avoid Voids is to keep your layout as symmetrical as possible early on. Don't try to get fancy with diagonal wings or weird L-shapes until you have a few upgrades. Stick to a grid. It’s boring, but it keeps you alive.
Also, keep an eye on the "Heat" levels of rooms. Some rooms are "hotter" than others, meaning they increase the difficulty of the puzzles in adjacent rooms. If you surround a high-value room with low-heat hallways, you’ll have a much easier time solving the central mystery of that floor.
The Visuals and Sound of Mt. Dunwick
The game looks incredible. It has this specific 70s-meets-1920s aesthetic. The colors are muted—lots of deep teals, mustard yellows, and, of course, that specific shade of "Blue Prince" cobalt.
The sound design is where the Inner Sanctum influence really shines. The floorboards creak. The wind howls through the vents. There’s no constant background music, just the ambient sounds of a house that feels alive. When a phone rings in a room three doors away, it’s genuinely startling.

It’s also surprisingly tactile. When you flip a switch or turn a dial on a safe, it has a weight to it. You can feel the machinery clicking into place. It’s that attention to detail that makes the puzzles feel fair. If something doesn't work, it’s because you did something wrong, not because the game glitched.
Common Misconceptions About the Game
A lot of people think this is a horror game. It's not. There are no ghosts chasing you. There's no combat. If you're looking for Resident Evil, this isn't it.
Instead, it's a "Mystery-Sim." The tension comes from the clock and your own dwindling resources. It's much closer to something like Outer Wilds or Return of the Obra Dinn than it is to Amnesia.
Another thing people get wrong is the roguelike element. Yes, you start over every day, but you keep your knowledge. And in Blue Prince, knowledge is the only progression that matters. You unlock "permanent" blueprints that you can carry over, but the real power-up is you, the player, getting better at reading the house.
Is it too difficult?
Honestly? Maybe. If you don't like puzzles or if the idea of restarting a map sounds annoying, you might struggle.
But for those of us who grew up on Myst or spent hours trying to decode the secrets of Silent Hill, this is exactly what we've been waiting for. It treats the player like an adult. It assumes you are smart enough to figure it out without a tutorial pop-up every five seconds.
Actionable Steps for Your First Run
If you're diving into Mt. Dunwick today, here is how you should handle your first hour:
- Focus on Key Fragments: Don't worry about the plot for the first three days. Just collect as many Key Fragments as possible. These allow you to buy permanent upgrades at the end of each day.
- Map the Fixed Points: Some rooms are always in the same place relative to the entrance. Learn these. They are your anchors.
- Carry a Notebook: I'm serious. Write down the symbols you see. Draw the weird diagrams on the walls. The game won't record everything for you.
- Prioritize Utility Rooms: If you see a card for a Workshop or a Tool Shed, take it. The items you find there are far more valuable than a "Gold Room" early on.
- Watch the Clock: When your stamina gets low, start heading back toward a "Safe Room." Don't push your luck. Ending the day on your own terms is always better than collapsing in a hallway and losing your inventory.
Blue Prince is a dense, layered experience that rewards patience and observation. It’s about the joy of architecture and the terror of a well-placed secret. Whether you're a fan of the old Inner Sanctum serials or just someone who likes a damn good puzzle, Mt. Dunwick is waiting for you. Just try not to get lost in the hallways.
