About Sticky Sticky: Surplus Protocol

Sticky Sticky: Surplus Protocol - about the game
About This Game

This is a co-op roguelike centered on expansion, connection, and loss of control.

In a future where humanity has vanished, artificial intelligence maintains a simulated version of human life.
You are not human, but slime-mold–derived lifeforms inhabiting abandoned toys and household objects, moving through enclosed, familiar, yet deeply unsettling indoor spaces.

Your goal is not to clear enemies, but to survive, spread, and endure within a system that is constantly breaking down—while searching for a chance to restore organic life.

Core Gameplay
â–  Core Expansion System

Players plant a single shared Core and continuously inject energy to spread the network outward.
Once energy is committed, it cannot be recovered. Move too far, and expansion stops.
Every decision is irreversible.

â–  Resource-as-Time Pressure

Food and resources are limited. Expansion itself consumes energy.
Delays, mistakes, or overextension will push the system toward collapse.

â–  Random Builds & System Mutation

Random items allow players to alter personal abilities, Core behavior, and even the rules of expansion.
Builds are not just power increases—they rewrite how the game functions.

Co-op Experience
â–  Cooperation-Driven Roguelike

All players share critical resources and expansion progress.
One player’s choice can save the team—or doom it entirely.

â–  No Fixed Roles, No Solo Play

Players may explore, supply energy, scout, or perform emergency recovery,
but no role is optional, and no one can survive alone.

Atmosphere & Tone
â–  Uncanny Familiarity

Clean living rooms, narrow bedrooms, AI-maintained domestic spaces—
everything appears normal, yet feels increasingly wrong.

â–  Psychological Pressure Over Combat

Fear comes not from pursuit, but from system imbalance, resource depletion,
and decisions that cannot be undone.

Key Features
  • Co-op roguelike with irreversible runs

  • Unique Core / Expansion / Energy systems

  • Highly randomized items and build paths

  • Emphasis on decision pressure and teamwork over mechanical skill

  • Light psychological horror, not jump-scare focused

If you enjoy system-driven gameplay, irreversible choices, and cooperative tension,
this game offers an experience distinct from traditional action or horror titles.
