Welcome to haruka_apps Laboratory
I make small games, creative tools, AI-assisted experiments, and CC0 recipes.
This lab is built from over 1,000 prototypes.
Most failed. Some worked. A few became little gems.
To me, AI is not a magic lamp.
It is a skilled carpenter, and the human still brings the taste, rules, and imagination.
Here you will find playable games, creator tools, and CC0 recipes for anyone who wants to make something.
My wish is to help the next generation of creators turn their words into worlds.
Welcome to the lab.
Horror chess in a dark interrogation room. Watch as eldritch tentacles devour captured pieces. Your move.
