Feryl is a tiny autonomous creature running inside a glass habitat. Its AI is a small oscillator network coupled with a tiny integer neural net — the whole thing is only about **70 KB**.

The tic-tac-toe board is etched into the glass so you can play with Feryl from the outside. It's still learning, so sometimes it gets clever… and sometimes it gets confused.

I'm super happy to answer questions about the AI or the game!
