Hang the crystals. Keep every beam from tipping. Finish perfectly level.
Tap a hook to hang the next crystal. Each beam tilts toward its heavier side, and the gauge above it shows how close it is to tipping. A crystal far from the middle pulls harder than one near it. A hanging beam counts as everything below it.
If a gauge goes past the red, the beam tips: the crystal falls, you lose a life, and you try that crystal again. Hang every crystal to finish the mobile. Finish with every gauge dead centre for a Perfect bonus.
Weights 1 to 4. Heavier crystals are bigger, and the beads on the wire count the weight.
