第三定律 THIRD LAW第三定律 THIRD LAW

Every shot is a step — and an inhale

THIRD 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 world

Sustained 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.

Seven chambers, fifteen to thirty minutes

• Ignition, Scatter, Storm, Vent Station, Wallbreak, Hot Gate, and a three-phase Core boss
  
• Inertia shards are rigid bodies: dense inhale levels you fast and can throw you into fire
  
• Four affinities: the third card in a line offers a unique key
  
• Swap weapons at the vent station; beating the run unlocks Overload from chamber 2
  
• All visuals and audio are generated in code — neon geometry, zero textures
