Icons at the bottom of level select

[ZestyOrang]

Does anyone know what the icons at the bottom of the levels in the level select screen indicate? Fire alarms and extinguishers are obvious, but what are the others? Also, what does it mean when they are highlighted?

They are all the types of collectibles. Fire Alarms, Extinguishers, Constellations, Chess Pieces and Blueprints. Grayed out means you are missing collectibles in that chapter. Fully white means you've gotten them all. If they have a red line with a circle, that means there are no collectibles of that type in the chapter.

Alarms and Extinguishers are usually placed in the open or are easily visible.
Constellations are hidden rooms that usually blend in with their surroundings. They could be behind doors, in shadows, or otherwise hard to find.
Chess Pieces are usually found out of the way in hard to get to places.
Blueprints are kind of the same as Chess Pieces, in that they are found in spots that you miss due to the game misdirecting you.

There are also literal easter eggs found in usually extremely hidden or hard to get to spots, but they do not count towards any collectible icons.
