Abyss Breeder Diary

Abyss Breeder's Log is a dark monster-breeding simulation told through text and pixel art. You hatch larvae, play training cards to boost their abilities, resolve TRPG-style events, and guide creatures through evolution. At the moment of collapse, you choose whether to dispatch them to the surface world or position them as territorial guardians—and once released, they never return. However, the genetic traits and characteristics they carry are inherited by future generations through bloodline. Beyond the maze lies the surface world. You command your creatures to raid, plunder, and burn cities to expand your territory through foreign conquest, defend your domain against real-time invasions using guardians, maintain a prison of captured intruders, and engage in dark dealings at a black market fueled by souls. The abyss connects the underground and surface through chains of causality, bottomless and unfathomable. Breed your own ultimate and abominable creature, then unleash it from the depths to the world above.
