第三定律 THIRD LAW

Every shot is a step — and an inhaleTHIRD LAW is a top-down zero-gravity roguelite. There is no WASD. Recoil is your only thrust. Firing opens a muzzle vacuum: inertia shards have mass, and inhaling them yanks the hull off course. Aim, movement and collection share one trigger. Heat is a sink. A full XP bar stops the worldSustained fire overheats and jams the gun.

Inhaling shards vents heat — and changes your heading. When the bar fills, time freezes: pick one of three rewrite cards to change a law of this run, or abstain to dump heat and heal 1 HP. Clearing a chamber no longer deals cards; it opens the door and repairs 1 HP.
