Keys and Unlocks Guide

Do the key route before serious sorting. The movement and carry upgrades reduce the cost of every future trip.

1Crimson Octagon KeyHigh JumpAt the very start of the game, look straight ahead. The key is hanging under the crest / wall emblem in front of you.
2Golden Diamond KeyCarry Capacity +3Near the crimson chest area, jump onto the stair railing decoration and look inside the vase. The key is inside the vase, not on top of it.
3Emerald Club KeyRunFind the scale table, then check the bench to the right of it. The key is buried under a pile of books, so clear the books off the bench.
4Azure Star KeyCarry Capacity +2Walk to the back wall of the second floor, away from the staircase. As you face the back wall, the key is on top of the last bookshelf on your right.
  • Crimson Octagon gives High Jump, and High Jump makes the stair-rail and bookshelf-top pickups practical.
  • Golden Diamond is next because it is in the same general chest/stair area and gives the larger carry upgrade.
  • Emerald Club comes before the far second-floor pickup so Run helps with the remaining walk and every later sorting route.
  • Azure Star is last because it is the longest key walk and gives the smaller carry upgrade.
  • Match chest symbols by shape: Octagon, Diamond, Star, and Club.
