Deep inside a glowing research lab, a friendly robot arm named Lumo keeps the reactors running. Its job is simple to explain and tricky to master: grab an energy orb in its claw and launch it into the right reactor core.
Every level is a work order. The panel at the top shows which core needs which orbs, for example two plasma orbs and one ion orb for the cyan core. Drag back anywhere on the screen to aim, follow the dotted preview, and let go to launch. Orbs fly with real gravity, bounce off walls and girders, and either drop into a core or fizzle out on the floor.
Charge every core before your orbs run out. Drop an orb into the wrong core and it overloads in a shower of sparks. Miss, and that orb goes to the back of the feed. Cryo orbs even shatter when they hit the floor. Finish with orbs to spare to earn up to three stars.
THE TWIST: MAGNETIC FIELDS
Every orb carries a charge. Plasma and flux orbs are positive, ion and cryo orbs are negative, photon and graviton orbs are neutral. Inside a magnetic field, positive and negative orbs curve in opposite directions while neutral orbs fly straight. The aiming dots bend with the field, so you can read each shot before you take it.
WHAT'S IN THE LAB
- 30 work orders across three sectors: Calibration Bay, Fusion Hall and Quantum Core
- Six energy orbs: plasma, ion, photon, graviton, flux and cryo
- New gadgets as you progress: steel girders, cores up on wall gantries, cores that drift along rails, force-field shutters that open and close, deflector plates on springy pistons and magnetic fields
- Ricochet shots off walls and girders earn bonus credits
- An orb rack shows the next three orbs, so you can plan ahead
MEET LUMO
A lab robot arm with a single camera eye that shows how it feels. Lumo coils back when you aim, snaps forward on every launch, smiles when a core comes online and glitches out when an orb overloads.
CHASSIS BAY
Earn credits by clearing work orders and spend them on new looks for Lumo: Prototype, Hazard Hauler, Circuit Lime, Phase Violet, Crimson Overdrive and Prism Core.
THE LOOK
Everything glows: neon outlines on a dark lab, swirling plasma rings, spinning radar screens, sparks, light columns and glossy floor reflections.
