"Core Gameplay Loop

Sprint (Run): Control your character to automatically or manually parkour forward on the track, avoiding basic obstacles.

Pass Through Math Gates (Calculate): Encounter gates marked with arithmetic operations (e.g., +3, -2, ×2, ÷2). Passing through a gate immediately changes the number of guns you hold according to the operation result.

Shoot to Defeat Monsters (Shoot): Use guns to defeat monsters on the path. Each shot consumes 1 gun. You must carefully manage your gun count, treating it as an extension of your ammunition.

Resource Management & Failure Condition (Survive): Ensure your gun count always stays above zero. If the gun count drops to zero due to operations or shooting, the game is over."
