Geometry Dash Shrill Hallway, an epic Medium Demon level rated 10 stars with 3 user coins, is a creation of the talented player Nico99. As the third level in the Doom Gauntlet, it stands as a significant challenge for players seeking intense gameplay experiences within the Geometry Dash community. One interesting aspect of Shrill Hallway is its use of the song "Haunted Woods," which is also featured in another level called Pureland from the Spike Gauntlet.
