Lumino City is Now Available on Steam! Sequel to the award-winning game Lume, Lumino City begins where that game left off. Begin by exploring the city, and using your ingenuity piece together all sorts of puzzling mechanisms to help the people who live in its unique world. Discover gardens in the sky, towers marooned high on an immense waterwheel, and houses dug precariously into cliffs. Three years in the making, it's handmade entirely out of paper, card, miniature lights and motors.
