blackhole and star

Game Description:

"Graviton Balance" is a physics-driven action game about harmony, inertia, and survival. You control a black hole and a star, eternally bound by gravitational tension, as they travel through a procedurally generated universe. Your mission: balance mass, avoid collapse, and keep moving — because stopping means destruction.

Every second you survive, every parsec you traverse, earns you Distance Points — the only remaining currency in this post-cosmic void. Spend them in the Singularity Shop to unlock new visual effects, mass presets, obstacles, and deeper game layers.

Core Mechanics:

• Dual Entity Control:
  You control the black hole by holding left-click — a directional vector appears, and when released, the black hole launches in that direction. The star reacts with an opposite impulse. Momentum is always shared.

• Mass Balancing System:
  Moving the black hole drains its mass and transfers it to the star. Moving the star does the reverse. If either entity loses too much mass, it collapses — one fades into a cold void, the other detonates in a gravitational implosion.

• Constant Motion Requirement:
  You must keep moving. Inertia isn’t just physics here — it's survival. If both entities slow down too much, gravitational resonance breaks and both are annihilated in a chain reaction.

• Scoring System:
  Your score is based on distance traveled. These Distance Points can be spent in the Singularity Shop, unlocking:

  • New visual styles for the star and black hole

  • Alternate gravity modes

  • New cosmic threats

  • Passive upgrades and mass configurations

• Obstacles & Threats:
  The cosmos is scattered with debris, gravitational warps, and the Red Vector — a symbolic, fast-moving red shape that hunts you if you stay idle. It represents a rupture in the mass balance, and when it catches you, the run is over.

Key Features:

• Unique Dual-Mass Simulation: Balance shifting energy between two entities — one collapse ends the run.

• Elegant Visual Design: Minimalist visuals, ambient backgrounds, glowing mass trails and responsive UI effects make the space feel alive.

• Immersive Gravity Physics: Acceleration, recoil, drag — every movement has weight and consequence.

• Procedural Universe: Infinite paths, randomly generated obstacles and galactic themes in every run.

• Singularity Shop: Use your score to unlock deeper mechanics, customization, and hidden gameplay layers.

Lore & World Concept:

In a post-universe void where entropy reigns, only two celestial relics remain: a decaying black hole and a burning star. Bound by a shared fate, they must keep each other alive through perfect balance. You are not just surviving — you're sustaining the last cosmic echo of existence.
