FIELD GUIDE

One light, two choices.

Click or tap a creature to strike it. Click the central crystal or press Space to restore its light. Every five seconds, the night drains a little light; creatures that reach the inner ring attack too.

Defeat creatures for star dust, then buy upgrades. Survive three minutes to finish the vigil, or choose Endless for a growing challenge. Upgrades last for this watch. A fresh watch starts evenly.

Keyboard: Left/Right selects a creature; A or Enter strikes the selected creature. Space repairs. P pauses. Number keys 1–4 buy upgrades. All buttons also support Tab and Enter.
