Sewer Dweller

 Game Overview

SEWER DWELLER is an endless, retro-arcade style underground survival game built using HTML5, CSS, and 3D WebGL graphics powered by the Three.js library. The game features a dark, neon-tinged, and atmospheric aesthetic where players control a unique underwater creature navigating a never-ending descent through flooded, hazardous sewer systems.

Core Gameplay Mechanics

The main objective is to dive as deep as possible, manage resources, and fight off underground threats:

• The Endless Descent: The player continuously swims downward through an procedurally accelerating tunnel. The score is determined by your maximum Depth in meters.
• Survival Elements: You must balance two vital meters:
  • Health: Decreases when taking damage from obstacles or when starving.
  • Hunger: Drains constantly over time. If your hunger hits zero, you begin to starve and rapidly lose health.
• Feeding & Collecting: Floating scraps are scattered throughout the tunnels. Eating scraps restores hunger, recovers a small amount of health, and awards currency.
• The Black Market (Shop): Players earn a currency known as Credits (◈) based on their depth, scraps collected, and enemies defeated. These credits are spent in a shop to unlock new playable creatures.

Playable Creatures

There are 6 distinct underwater creatures you can unlock and play as, each with unique stats (Speed, Health, Appetite, Reach, Gas Resistance) and a signature Spacebar combat move:

Creature	Classification	Signature Move	Description
Tadpole	Balanced Starter	Bubble Volley	Average stats; fires a 5-bubble spread shot forward to pop enemies.
Sewer Eel	Speed / Glass Cannon	Volt Discharge	High speed but fast hunger drain; unleashes chain lightning hitting all nearby targets.
Grime Puffer	Tank	Spike Nova	Slow but has high health; detonates a $360^\circ$ burst of piercing spikes.
Lantern Angler	Utility / Explorer	Blinding Flash	Possesses a built-in magnetic pull for scraps; flash-stuns and burns enemies ahead.
Ghost Koi	Specialized Phantom	Spirit Wave	Highly immune to toxins; releases a piercing soul-wave that grants brief invulnerability.
Dino Fish	Apex Leviathan	Apex Chomp	Secret endgame creature with colossal health and a massive lunging bite.

Zones & Environmental Hazards

As the player descends deeper, they transition into more dangerous regions, marked by changing neon fog colors, rising water currents, and faster enemy spawn rates:

1. The Drains (0m+): The starting zone with a green hue. Features standard Rats that swim erratically and toxic Gas clouds that drain health and hunger upon contact.
2. Flooded Tunnels (200m+): Blue-hued zone where obstacles speed up and predatory Leeches begin spawning, which actively hunt down and lock onto the player.
3. The Rot (700m+): An intense, reddish orange layer with highly aggressive, high-health variants of enemies.
4. The Abyss (1300m+): A purple, hyper-fast terminal zone testing player reaction times against overwhelming hazard rates.

Controls

The game features responsive input styles adapted for both desktop and mobile layouts:

• Movement (PC): W A S D or Arrow Keys to tilt and navigate the creature around the circular inner perimeter of the tunnel.
• Attack (PC): Spacebar triggers the equipped creature's signature cooldown ability.
• Mobile/Touch Controls: A drag-to-steer mechanism on the screen paired with a dedicated floating virtual "MOVE" button in the bottom right corner for attacking.
