All 11 Realms
Not colour themes. Each Realm is a complete visual universe with its own environment, its own residents, and its own way of showing your Loop growing.
Toxic Swamp
Something is leaking. It is probably fine.
Voidcore
It is very quiet out here and something is watching.
Candy Chaos
Offensively cheerful. Do not look directly at it.
Inferno City
The pavement is warm. Nobody mentions it.
Glitch Realm
This realm was not supposed to still be here.
Celestial Dream
Soft, endless, and slightly too far away.
Hero
Someone left a light on for you.
Misthios
The mountain has been humming for a thousand years.
Flora
Everything here is ending beautifully, and none of it has stopped.
XYVIEX
This should not be openable. It is open.
Empathy
Somebody kept a light on and a seat free, long before you got here.
