Lumen Bloom — Evolution from Light Dust to Cosmic Web
60Hzfixed-step feel

Eight Stages of Evolution

Each stage transforms your appearance, sound, and relationship with the world around you.

Stage 01
Light Dust
Fragile
A barely-there speck. The world feels vast and dangerous. Even a brush with a larger entity threatens your existence.
Stage 02
Droplet
Curious
Gaining cohesion and confidence. Magnetism pulls nearby motes toward you. The world is beginning to respond.
Stage 03
Ripple
Rhythmic
Rings radiate as you move. Your blob perimeter begins to deform visibly with each absorption event.
Stage 04
Moonlit Lake
Serene
Reflective and calm. The camera has zoomed out enough to reveal the full neighbourhood. You belong here.
Stage 05
Star
Radiant
Warmth and light emanate from you. Smaller entities orbit. A warm procedural soundscape wraps the world.
Stage 06
Nebula
Expansive
Edges blur into colour. You're becoming something larger than a single point — a region, not an entity.
Stage 07
Galaxy
Sovereign
Spiral arms extend. The camera reveals a breathtaking scale. You've become a world unto yourself.
Stage 08
Cosmic Web
Sublime
The final form. Threads of connection span the universe. You are no longer a point — you are everywhere at once.

Built for Wonder

Every technical choice serves the feel — calm, tactile, and alive.

◎
Organic Blob Physics
Your entity is a closed perimeter of spring-connected points. It deforms as you absorb motes, collide, and navigate — not a rigid circle, but a living mass.
♬
Procedural Soundscape
No audio files. Ambient music is synthesised live via the Web Audio API — sine sweeps, harmonic layers, and absorption chimes that evolve with your stage.
⚡
60 Hz Fixed-Timestep ECS
Deterministic physics at 60 Hz, decoupled from rendering. Consistent across every device and refresh rate, with full replay support for testing.
📴
Offline-First PWA
After the first load, Lumen Bloom runs without a network connection. No account. No telemetry. No advertisements. Ever. Just the game.
⚙
JSON-Driven Balance
All physics constants, stage thresholds, and enemy behaviour live in config files — not hard-coded. Tune the feel without touching source code.
⌨
All Input Modes
Keyboard, mouse, and touch are all first-class citizens. Automatic priority arbitration ensures the best input device always wins.
