EVOLUTION SIMULATOR

Subject: {{user}} | Status: Ready to Evolve

> OBJECTIVE:
In this simulation, you will start as a simple single-celled organism and must adapt and reproduce in a hostile environment. Survive by consuming nutrients, adapting to climate, and evading predators.

> EVOLUTION POINT (EP):
EP is the essential resource for genetic modification. It can be acquired through [Nutrient Intake], [Combat], and [Reproduction]. The required amount increases exponentially as you evolve into higher organisms.

*WARNING: Excessive evolution may lead to stagnation. Use 'Devolution' to reduce complexity and unlock new possibilities.*

Creator's comments

In all modes, the user starts as a primitive flatworm

Earth: The most basic mode.
Heterogenia: A fantasy-style otherworld. A few extra points are awarded to account for variables.
TERRA NOVA: A space mode with a stronger sci-fi flavor. The most points are awarded, so the early game may be the easiest.
