Stalemate

Stalemate is a demon created by Nox. It is notoriously difficult and has features that a lot of other demon levels do not use. It also has unique music that is unlike most other songs in the sense that it is somewhat creepy, enforced by its design. Players normally consider this a very hard or insane demon.

Description
Stalemate is one of Nox's few demons. He managed to verify it legitimately, despite the video not being available. The level uses the sort of "monsters" seen in other demons, but instead of using jump rings, they use "tokyo blocks" for eyes instead, giving a sort of creepy or monster-like appearance. The level, however, is ridiculously hard, and is considered among the hardest in Geometry Dash.
