Circleum

A world within a circle—
Have you ever imagined a realm where every circle holds another universe?

Circleum is an idle game that begins in pure black and white,
and gradually fills with color as time passes.
Explore a fractal world of endless circles,
where fairies battle, grow, and unlock new layers of existence.
