What is Primordialis ?

Primordialis is a physics-based roguelike fish builder game. Set in the mysterious and ancient primordial ocean, you are tasked with creating your own unique sea creature from over 60 types of cells. Whether you opt for explosive, electric, venomous, or stealthy abilities, the possibilities are nearly endless.
The game encourages creativity as players craft creatures that survive the harsh underwater world. With its deep creation system, each part of your fish serves a function—movement, attack, defense, or utility.
