Deep beneath the mountains lies a cavern of living crystals! Guide your roots through the glittering underground maze where amethyst walls and quartz formations create a breathtaking but treacherous landscape. Drag to direct roots between crystal formations, absorb sparkling mineral nutrients for growth energy, and bloom radiant crystal flowers at cavern exits. Crystal shards are sharp — roots that touch them take damage. Each chamber introduces new crystal types: growing crystals that slowly encroach on your paths, reflective crystals that bounce your growth direction, and unstable crystals that shatter when roots pass nearby. Higher chambers feature tighter crystal corridors, faster crystal growth, and mineral deposits hidden behind dangerous formations. Root health drains in the mineral-depleted zones — reach crystal-rich areas to replenish. Navigate the shimmering labyrinth, harvest the minerals, and transform the cavern into a brilliant underground garden.
