| Star Key |
The Star Key is a type of key with a star-shaped point used throughout the fifth Shadow Geyser.
The Star Key is required to unlock doors to advance further into the Geyser. Two Star Keys may be obtained. The first is used to unlock a door in the Glade that leads to a chamber inhabited by Core Creatures.
The second may be used on a metal door on the bottom-left of the main menu which is hidden by a block which can be kicked away, revealing a room with a machine containing the game's soundtrack and a man who can completely reset the game.
