About this game

Primordialis is a physics-based roguelike fish builder. Unleash your creativity to defeat creatures using venomous tentacles, electrical shocks, or exploding children. The possibilities are endless. Explore the primordial depths to reveal its secrets and discover what lies beyond.

================================= Create ==================================

The core of Primordialis is its simple yet deep creature creation system. Your body is constructed out of cells which each have unique properties and functions. With over 60 cell types to place and combine, there are countless creative combinations you can use to engineer your perfect fish.
You are given the freedom to play how you want, whether you want to be a massive serpent that swallows other creatures whole or to tinker with complex mechanisms and circuitry. Your only limit is your imagination.

================================= Survive =================================

In the main rogue-like mode, you embark on a difficult journey of growth and evolution. Explore the world and learn to deal with a diverse ecosystem of hand-crafted enemies, all built using the same creature creation system as you. Discover cell types, mutations and more to help you survive in this harsh and brutal world. Traverse the 5 main biomes and discover what lies at the end.

You can also play in sandbox mode if you want to perfect your creature design plans before a run, study the biology of your enemies, or just enjoy some relaxed creature building.
