Read pulse telegraphs, reshape the ruin, and commit to a path that stays safe after the terrain reacts.
Read the ruin
A compact isometric tomb stays fully on screen. Pale stone slabs step from height to height. Interactive slabs and the relic glow with a soft violet light. Numbers on unstable floors and traps count the pulses until they change.

Every step and every interaction advances a shared pulse. Raise a slab to open a stair. Turn a one-way arrow to open a corridor. Watch the countdown, then commit to a short path that still works after the ruin reacts.
Claim the relic
Reach the violet relic, then the exit. Early chambers share both on one terrace. Later chambers separate them, add collapsing floors, and ask you to leave the way you came before a trap springs.

Five short chambers teach one idea at a time: raise, read a pulse, race a collapse, turn an arrow, then secure the relic and walk out.
Controls
- Tap a highlighted neighbor to step.
- Stand on a glowing slab or arrow and tap it to raise or rotate.
- Tap Undo to reverse the last action, or Restart to reset the chamber.
- Tap Next when the relic is secured.
