Pulse a tiny isometric landscape until a luminous signal crosses its shifting strata.
Gameplay
A compact 5×5×5 terrain puzzle. Each pulse raises a local cross of soil columns through low, resonant and high strata; high peaks fracture back to low. Shape a continuous resonant contour so energy can propagate from the gold source crystal to the cyan target.

Read the strata
The gold crystal is the source and the cyan crystal is the target. Middle-height columns glow with resonance, but the signal only crosses columns that touch edge to edge. Tap one soil column and its movable neighbours rise with it. A high peak fractures back to low ground, so one pulse can open one route while breaking another.
Stone columns never move. Early stages teach the terrain cycle; later relays add bedrock, bends and false echoes. The pulse counter is your whole budget, so inspect the local cross before committing.

Controls
- Tap or click a soil column to pulse its local cross.
- Tap Restart to restore the current puzzle.
- Tap New Seed for another landscape at the same stage.
- Tap Next Stage after completing a relay.
