Poolrooms hints

In The Poolrooms, players can encounter various writings on the walls that appear to be drawn with black crayons. These writings are randomly generated and provide hints or context for gameplay and lore.
"Friend?" This message is accompanied by a simple doodle of Goober’s face. The writing suggests that Goober is not hostile and may be seeking companionship.
----
"How do I get to the balconies?" This message may have been a trace left by lost ARC test subjects trying to escape the level. This message's goal is to help others by guiding them toward the balconies found in The Poolrooms, as they are required for progression.
----
"I hear it whispering" This writing warns about the Whispering Wyrm, an entity known to reside in The Poolrooms. It hints at the presence of this entity for players who may not have encountered it yet.
----
"The chlorine burns" This message informs players about the danger of water in The Poolrooms. If the player’s camcorder is exposed to water for too long, it will stop working. Since the game is presented as found footage, the loss of the camera’s recording effectively ends the game, simulating the player's death.
----
"Dont open your eyes underwater" This was an earlier version of the warning about water hazards. It was replaced in a later update by “The chlorine burns” for the sake of simplicity.
