History of Chamber of Wishes

The Chamber of Wishes is a bonus room in The Coil that is reached with a high score. Score comes only from Wishing Glass collected by the fireteam, from enemies, breakable pots and rare Glass Collectors; glass that falls into pits or inaccessible areas is lost. Destructoid cites a Platinum score of 150K+ as the target.

The A Place of Dreams triumph is tied to entering the room during a run. A forum report from a few years ago described players not receiving the triumph after reaching the room, so check whether that has been fixed.
