Follow the flux.

Burrow through circuitry. Gather every energy crystal and reach the portal. Watch what you leave hanging above your head.

Unassisted attempt

Personal scoreboard · unassisted runs only

Best moves per cave, then fastest time on a tie. Scores are saved only on this device. Solution previews and autoplay never earn scores. Restart for a fresh unassisted attempt.

Field guide

Mint diamonds are energy crystals. Copper circuitry can be dug away. Steel walls are solid. Silver orbs and crystals fall when unsupported and roll off rounded objects; a falling object is fatal. Push silver orbs sideways into empty space. Red sentries patrol open tunnels, turning clockwise when blocked. Collect every crystal before entering the portal. Restart any cave at any time. Progress stays on this device when browser storage is available. Sound starts after your first interaction. Music has its own toggle and pauses with the game. Show solution restarts the current cave and previews its route; Auto solve restarts and follows that route. Both mark the attempt as assisted and exclude it from the personal scoreboard, even if you hide the solution or stop autoplay. Restart begins a new unassisted attempt. Fullscreen availability depends on your browser; the game also fits a normal window.
