1. The Golden Rule of Puzzles

Before you stress over a locked door, remember this: Push the Dungeon!

Many puzzle items (Keys, tools, specific stone symbols) only drop by reaching deeper floors. Some items drop as late as Floor 950. Usually, you receive a new puzzle item every 50 floors. If you are ever stuck or missing something, grind deeper. Also, remember to speak with Charon for subtle hints.

2. Early Tools & The Ghost Puzzle

In the early game, you will use basic tools to open up the camp and sewers.

Basic Tool Locations

  • Keys: Extinguish the fire to get one; find another by using the Lantern to light up the pile in the Backroom.
  • Crowbar: Use it on the cracked Barrel to get Dynamite. Use it on the Coffin to open a new passageway.
  • Lantern: Use it to navigate the rift/crack beyond the camp safely.

Using Dynamite

Use the Dynamite on the crack in the Sewer Room (right of the camp) to open the passageway to the Ghost Room and the locked stairset.

πŸ‘» Step-by-Step: Releasing the Ghost

  • Step 1: Go to the round object next to the Trader and pull the lever to open the water flow in the Sewer.
  • Step 2: Impale any Familiar on a spike in the Impale Room to create blood.
  • Step 3: Buy the Skull Amulet (Instakill Medallion) from the Equipment store.
  • Step 4: Go to the Ghost Room. With Blood and Water active, use the Amulet. The Ghost will disappear, granting you a new Inscription for the mirror.

3. The Spider & The Mushroom Dimensions

After inputting the Ghost's inscription, enter the left door through the wall crack to meet the Spider.

πŸ•ΈοΈ Surviving the Spider

Click and hold to remove the webs, but this draws the Spider closer. To survive: Open your map for a few seconds to "hide your eyes." While the map covers the screen, the Spider will leave.

πŸ„ The Mushroom Statue & Eye Sequences

Past the Spider is a room with a Mushroom statue holding a copy of the map on its desk. Insert your Medallions (Round Gems) into its sockets. You must travel the map mimicking the exact sequence to trigger effects.

Green Eye Sequence

Code: Top - Middle - Middle - Right - Left - Bottom

Result: Transports you to the upside-down Green Mirror Dimension.

Blue Eye Sequence

Code: Bottom - Bottom - Right - Right - Left - Top

Result: Unlocks a new Trader area where you can exchange Hemalith for massive % boosts.

4. The Well, The Mirror World & The Angels

Changes in the Normal Dimension affect the Mirror Dimension, and vice versa. Follow this exact sequence to solve the late-game puzzles:

  1. The Coin: Turn off the fire in the Normal World. The fire in the Mirror World will light up, allowing you to grab the Coin. Drop the Coin into the Normal World Well for an Inscription.
  2. The Saw: In the newly opened room next to the Well, click the bell, select the Rope (found in the Blue Eye area), and ring it to get a Saw.
  3. The Crank & Shovel: Make sure water is OFF in the Normal World. Go to the Mirror World Sewers. Use the Saw on the sewer grate. You will find biomass/meat on the floorβ€”use the Shovel on the biomass to extract the Crank.
  4. The Torch: Install the Crank on the Normal Well and use it. Go to the Mirror World room (where you placed the Ladder) and grab the Metal Rod. Place the Rod on the pedestal in the Room of Eyes and hit it to get the Torch.

πŸ‘Ό The Angel Statues & Final Code

Give the Torch to the Left Angel. To get the final deciphered code:

  • Save your game.
  • Exit to the Main Menu through the in-game settings (Do NOT close the game).
  • The code will reveal itself on the right side of the main menu.
  • Load back in and type it above the Mirror.

To open the Final Boss Door: You must input all codes AND complete a single, unbroken run from Floor 1 to 1000!

🀫 Hidden Camp Secrets & Tips

🐾 Healing Wounded Familiars

If your familiar is injured, you can heal it! Go to the Green Mirror Dimension. Near the sewer grate, there is a hidden altar. Interact with the altar while carrying your wounded beast to restore it.

πŸŽ’ Leftover Inventory Items

Don't panic if you reach the end of the game and still have the Crowbar and Shovel in your inventory. Once the Angel Statues are activated, these items become "dead weight" and are no longer needed. Just head to the final door!

πŸ† "Nice Try" Hidden Achievement

If you buy the Skull Amulet (Instakill Medallion) from the shop, don't just use it on the Ghost or a Boss! Try using it directly on the Hole (God) screen to unlock a secret achievement.
