Mini Monster Terrarium

A zero-player system of 3 connected biomes that spawn creatures and food.

Pick some starting parameters (or use the defaults), hit Start, then just watch!

Parameters

• Resources: Material for spawning monsters and food.
• Decomposition Rate: Rate to consume dead monsters and waste for conversion to resources.
• Max Saturation: Max amount of decomposed material that can be held for conversion.
• Conversion Rate: Rate to convert decomposed material to resources.
• Major Spawn: The monster or food the biome will spawn a large number of.
• Minor Spawns: Monsters or food the biome will spawn a small number of.

Monsters

• Leaf Cutter: Small, short-lived, eats Plants, produces little waste.
• Fang Mouth: Medium, middling lifespan, eats Meat and dead monsters, produces some waste.
• Jewel Eater: Large, long living, eats Crystals, produces a lot of waste.

Mechanics & Indicators

• Well-fed monsters live longer; starving monsters live shorter.
• Starving monsters will move to another biome if there's food there.
• Grayed out monsters are sleeping; blacked out monsters are dead.
• Red bars below biomes indicate unused resources. Biomes need resources to spawn anything.
• Some parameters will create a stable, dynamic system; others will eventually degenerate.
• Speed things up or slow things down with the Time Scale slider.
