第三定律 THIRD LAW
Released 29 September 2026 · PC · Action, Indie

Your gun is your engine. Recoil is movement; firing opens a vacuum that pulls in mass-bearing shards and yanks your heading. A full XP bar stops time: rewrite one physics law, or abstain to vent heat and heal 1 HP. Seven chambers, 15-30 minutes.
Story
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
