Chamber of Time



The  Chamber of Time is a secret feature of Geometry Dash, being introduced in Update 2.1. It is located through a door in the center of the Coming soon page of the main level slider, but is hidden until the orange lock in the Basement has been selected, and the door's hidden location has then also been physically discovered. After doing so, the door will remain locked until the Master Emblem has been purchased from the secret shop, where then the Chamber of Time can be accessed.

Description
The Chamber of Time contains a text field and a feline ring-handle button below it, going by the name, the Gatekeeper. Pressing the button will cycle through a series of responses and clear any input in the text field. Entering certain phrases will unlock Icon Kit rewards as well as any related achievements. Hints in the form of green phrases are provided every so often to help guess the codes. Initially, there is a chest in the lower left corner which contains an orange key for the orange lock in the Basement.

Rewards
Enter the codes stated as captions to unlock the respective rewards.
