About This Game

A peaceful farm. A mysterious crash. A lost girl with cat ears… and no memories.

The Book of Tornaluna Cats 🌙 is a cozy, story-driven game about care, trust, and uncovering the past.

You found Tanya in a crater — injured, confused, and without memories.
As you take care of her — feeding her, healing her, reading together — something deeper begins to grow.

Her strength slowly returns.
Her memories begin to surface.
And with them… so does the bond between you.

This is not a game about danger or fast action.
It is about slowing down, building a peaceful life, and discovering who Tanya truly is — together.

🎮 Gameplay

Your main goal is to take care of Tanya and help her recover. You can interact with her in different ways:

  • Talk with her

  • Cuddle with her

  • Read stories together

  • Feed her

  • Heal her when she is sick

But caring for Tanya also means providing for both of you.

To obtain food and medicine you will need to:

  • Work on the farm

  • Fish at the lake

  • Explore the forest to gather ingredients and medicinal herbs

With the resources you collect, you can cook meals and prepare medicine to help Tanya regain her health.

You can also visit the village shop to buy ingredients, recipes, and books to read together.
