THE WORLDS OF THE CASTLE

The Castle is played across five worlds, each with its own landscape, soundtrack, room set and three hidden objects. These pages describe what each world contains, how it is structured, and what it takes to complete it — written for players who want to know where they are going before the next door decides for them.

The Castle

Level 1 — stone corridors, torchlight and the first three objects

The Castle is where the game begins and where it teaches you its rules without ever writing them down. You wake on cold flagstones with no name, no memory and no idea how long you have been lying there. There is a torch guttering somewhere down the corridor and, in every direction, a door. This first level is deliberately claustrophobic: bare stone, low ceilings, the sound of water somewhere below. It is a level about learning to lose gracefully, because you will lose here many times before the last door finally opens.

The Garden

Level 2 — daylight, overgrown hedges and things that were once tended

You escape the Castle and step into light. The Garden is the game's exhale: a vast estate garden that someone laid out with enormous care and then abandoned for long enough that the design is barely readable. Straight formal avenues dissolve into thicket, a fountain still runs into a basin full of leaves, and the hedges have grown high enough to become walls. It looks safe. It is not measurably safer than the Castle — the doors are still coin flips — but for the first time you can see the sky.

The Mountain

Level 3 — lakes, storms, stone trolls and the way into the deep

Bare earth beneath your feet, then stone. Ahead the ground tilts up and up — a mountain, vast and grey, its shoulders wrapped in mist. The Mountain is the level where the game stops being an escape and becomes a journey. Four of its five stages happen entirely outdoors, climbing from waterlogged lowlands to snow, and the fifth turns the whole thing on its head by pushing you underground.

The Mine

Level 4 — dwarven halls, ore, a tomb and something in the water

You find yourself in a long, dark, abandoned mine shaft. Stone dust and pine resin from the fallen torches grip your nose, and a cold wind comes up from the deep. You seem to remember passing through tunnels like this before — or perhaps through this exact one. The Mine is the darkest level in the game and the one that leans hardest on the feeling of being very far under a great weight of rock.

The Core

Level 5 — a hollow world, a rocky sun and a way back to the surface

Below the Mine the rock ends and the world turns inside out. The Core is a sphere within the planet, lit permanently by a molten sun hanging in its centre, with the landscape curving up on every side instead of falling away to a horizon. It is the strangest level in the game and the one where the art style shifts: still pixel art, but denser and more detailed, as though the game itself had jumped a hardware generation between the Mine and here.
