Cardume You are underwater. Sixty fish drift around you in the half-light. One of them is not a fish. It is wearing the shape of the school, and it is learning. When the timer runs out, it stops pretending. You will not survive that. #GameDevComIA

About This Game

Install: unzip the whole folder and run Game.exe. Keep Assets/Fonts next to it — the game reads its font from there, and writes your high score beside the executable, so avoid running it from inside the zip or from Program Files.

Windows SmartScreen will warn you that the publisher is unknown. That's normal for an unsigned indie build — "More info" then "Run anyway".

The Journey of Making This Game

Have been short and fun, the ideia of create a concept so easily and someday refine and be a real game, is great!

How Uniday Studio Helped

Uniday created a masterclass teaching how to use claude code and generative IA to be your custom engine in C++, I appreciate the way he pushes you to delivery something, I think this is what blocks most of the people working with this.
