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.
