Sticky Sticky: Surplus Protocol

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

■ 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.

■ Resource-as-Time Pressure

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

■ 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

■ Cooperation-Driven Roguelike

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

■ 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

■ Uncanny Familiarity

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

■ 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
