I will be leaving for vacation within the next couple days. Will still be around but will not be able to make any new fixes until I get back. I have left Masternerd as an Admin to the forums in case I miss anything. If you have any other questions while I'm gone feel free to ask any of my Discord mods.

Best I could do for fixes before I left was an optional patch, right click Uagi in game library, properties, betas, uagibeta2058. Hope this helps a bit.

Until we meet again!

Holiday Hotfix

Well Hello There!
Very sorry as I have had to patch yet again. this should be it for a while, hopefully Uagi can settle in a bit. Planning on releasing an optional patch right before I leave with a few Steam achievements and some other tidbits. Patch notes below, enjoy your holiday! UG

The Hidden Keys!
It seems two of the four hidden artbook keys have been activated! congratulations to those that have found them. That means that there are still two left, look through Uagi patch notes to find the last two!

Thanks to everyone for the feedback and bug reports, it helps a great deal.
Tell me what you think (good or bad) in a review, those help too.

“Uagi-Saba has so much added depth to it; it makes Fallout Shelter seem like a puddle in comparison.”
9/10 – The Insatiable Gamer

“Always wanted to breed mystics and create your own underground city? In Uagi-Saba, you can do just that.”

About This Game

What Is Uagi-Saba?

Uagi-Saba is a creature care simulator that takes place deep underground. Raise, care for and breed magical beings known as Mystics while harvesting resources, expanding sanctuary and exploring.

In-Depth Genetics

Uagi-Saba uses a realistic genetics system, every body part has two genes which can be passed on from parents to offspring resulting in thousands of body part combinations. Stats, skin pigment and many other parts of a mystic's DNA also have their own unique genes and can be passed on through breeding.
Recessive and dominant genes, resistance to sickness, mutations and the incorporation of "wild" genetics. It's all possible...


Raise mystics from egg to adult, feed them, give them water and keep them company.

Teach mystics a variety of words to better understand what they are trying to say.

Breed your mystics to discover new body parts and genes. Improve stats and traits through selective breeding, create the perfect species.

Play In The Gene Pool
Find new genes and mutations by breeding multiple generations of mystics. If you are lucky you may even stumble on a wild mystic, breed it with your own to uncover very rare genes.

Harvest The Harvest-able
Harvest all kinds of resources using special modules, rooms and your mouse pointer. Create a strong economy, expand your sanctuary.

What Was Lost Is Now Found
Find lore books long forgotten and read about the past or build a dig site to dig up old artifacts all with their own backstories.

Build It, They Will Come
Attract the local populous and grow your tribe through the construction of housing.

Grow, Bake And Ferment
Grow your own mushrooms, bake them into cakes or ferment them into elixirs for your mystics.

Come on by and tell me what you think.

"A species at the end of it's line encased in a speedy ship, travelling across the stars with a sleeping creature in it's underbelly.
Hoping to rekindle the fire, a second chance at life they sped towards the planet to find their sanctuary.
But it the end what they found was only the darkness and a slow death.
They were playing with very life itself and now they would pay with their own.
Sometimes though from death springs new life and something below that cold soil still moves." The Writings of Uagi-Gretumo-Saba
