21:14
Player meets the lunar queen and is surprised to find out she is human.

At 27:38 you're fighting the lunar queen on a flat plane inside a spherical planet.

That's the green spherical planet you saw at 20:09 and at 27:38 you're inside of it.

The sky is green because the surface of that planet is green.

Also the ceiling/dome is covered by fog but you can still see it if you pay attention.

I wonder what's the subliminal here lol.
