OOZE

You are the monster.

Fifty-four thousand years after its creators vanished, sample O-7 wakes up in a ruined lab overgrown by forest. It is hungry. And this world is only the first of many.

Every cell of the world is real. Roofs come off, walls dissolve, thatch burns, gunpowder blows up whole streets, towers fall together with their archers. Every house is furnished inside — and edible.

You don't steer the slime — you tempt it. Drop it, lay a pheromone trail, and it grows, eats, splits and adapts on its own. Hold it back when the cannons fire. Spit, lash out with tentacles, scatter spores — and let it decide the rest.

A journey across realities

The lab that made O-7 was built to cross the Threshold — the gate between worlds. Each world has its own laws, its own people and its own way of fighting back. The crossing always drains the slime, so in every new reality it starts weak and has to adapt again.

• The Medieval World — playable now. A seeded human race slid back into the middle ages: villages, monasteries, castles, and a King with his whole army.
• The Valley of Mages — in development. A land soaked in leaked aether, ruled by an order of mages: rune golems, elemental masters, exploding mana crystals, spells falling from the sky — and the ruins of the ones who made you.
• Further out — planned. A place called the Abyss that is in no catalogue at all. A dried-out desert where water is worth more than gold and the fortresses walk. More realities are catalogued, from calm to lethal.

What's in the early build

• The whole medieval world: 16 story levels in three acts and a finale — from pitchfork-wielding peasants to castles full of catapults and a royal army with cannons and home-brewed napalm
• The King himself, waiting behind his army — eat him whenever you like, or save him for last
• A secret bonus level, if you can find the one man who knows the way
• 4 abilities with 3 branches each: acid jet or bombard, hard shell or feeding frenzy, toxic cloud or hunter spores, long whip or battering ram
• 13 mutations, a hidden threat that grows with your power, and a nanite forge to push past the limits
• Biomes: meadows, autumn woods, snowbound fortresses, a village inside a mountain
• V.E.L.A — the lab's damaged AI narrator — and hidden lab logs that tell why you were made
• 50 achievements with pixel icons, a genetic archive with rare specimens, slime skins, challenge stars
• A sandbox: a huge map of every biome and a fortress that never stops sending armies

Made in code

Every graphic in OOZE is drawn in code — terrain, buildings, people, siege engines, fire, even the achievement icons. No sprites, no AI-generated images. Built with Godot 4 (C#).

System requirements

• OS: Windows 10/11 (64-bit) · Linux x64 · macOS 14 Sonoma or newer (Intel or Apple Silicon)
• CPU: 2 cores (4 threads recommended for the big battles)
• RAM: 2 GB (the game itself uses about 0.5 GB)
• Graphics: Vulkan or OpenGL 3.3
• Disk: 250 MB

Runs on older PCs too: automatic OpenGL fallback, a low-quality mode (on by default on 4-thread CPUs) and an FPS limit.
