What is Lumen Grove?
Lumen Grove is a ball sort game where you lift glowing orbs one at a time and drop them into glass tubes until every tube shines with four orbs of one color. There are always two more tubes than colors, from 2 colors in 4 tubes at the start to 8 colors in 10 tubes in the final Starbloom Dome chapter. Each orb also wears a white symbol, so a leaf or a crescent tells colors apart even on a dim screen.
