What's in the Room?

This is a Mirror Universe puzzle, created for a puzzle by Carl Worth. I would recommend at least having familiarity with the Spiral Galaxies genre before trying this out.

The clues are laid out so that it (mostly) looks like the word "room." This is my first paper puzzle, so please forgive any jankiness.

Rules (also in the PDF):

Divide the grid along the indicated lines into connected regions – “galaxies” – so that every cell is part of one galaxy and every galaxy has one circle clue inside it.

If the galaxy contains a plain circle without any lines, the galaxy must be rotationally symmetric with that circle being the center of rotational symmetry.

If the galaxy contains a circle with a horizontal, vertical, or diagonal line, the galaxy must have mirror symmetry when reflecting across the line given in the circle.

Treat shaded and unshaded circles the same while solving.

After solving, shade in the regions which contain shaded circles.
