Evolution Pops

Evolution Pops is an observational sandbox rather than a goal-oriented game. There are no scores, wins, or losses; you simply sit back and watch a tiny world unfold on its own.

Each cell is governed by a neural network with 88 weights. It isn’t programmed to "seek out food"-it discovers what works through trial and error. Cells that manage to find grass and reproduce pass on their traits to the next generation, while those that just spin in place eventually die out. Within minutes, you’ll see the creatures’ behavior become purposeful-all without a single line of hard-coded rules.

Features of this world:

- Three types of creatures – herbivores, predators, and scavengers-each with its own cost of living and survival strategy.

- Day and night cycles – herbivores tend to lie low at night, while predators gain an advantage.

- Catastrophes – droughts, plagues, infestations, or sudden, drastic drops in temperature.

- Brain evolution – the traits of the most successful individuals are passed on to future generations, even if the species faces total extinction.

- **Lineages** – track which bloodlines currently dominate the world.

- "God-like" tools – grow grass, scorch the land into a wasteland, or strike down an individual cell.

For those who want to observe closely, there is a dedicated panel for any selected cell, displaying its energy, age, activity level, and all 88 of its neural network weights. The interface also includes a mini-map, a population graph, a generational table, and an event feed.

Controls:

- Left-click - select a cell

- Right-click + drag - move the camera

- Scroll wheel - zoom

- Spacebar - kill half the population

- H - hide the interface

- Esc - pause menu

The game automatically pauses when a rare event occurs, ensuring you don’t miss anything.

Built from scratch using Godot 4. No textures are used; everything is rendered via code.
