Sure! Here's a simple implementation of the game you described:
Kitten Treat Hunt
This game creates a 3x3 grid where the player controls a kitten using the arrow buttons on the grid. The goal is to find the treat (represented by a pictogram) hidden in one of the cells. Once the player finds the treat, they receive a message indicating that the kitten is growing up. Subsequent attempts to find the treat will result in a different message indicating that the kitten is already fully grown.
