I built Pixel Pets, an open-source virtual pet family for M5Stack devices.

It currently supports:

• Muffin — CoreS3 + Module-LLM, with offline voice interaction
• Visu — CoreS3 without the LLM module
• Goo-Goo — Core2 version
• Pip — StickC PLUS2 / PLUS2 S3 pocket companion

The pets have moods, needs, mini-games, sounds, touch/button/IMU interactions, weather and moon-phase awareness, and ESP-NOW friendships.

Pip can send treats and gestures to a bigger pet via ESP-NOW.

The project started as a father-and-son maker project and is meant to be playful, hackable and parent-friendly.

No cloud account, no tracking, no subscription.

I would love feedback from other M5Stack users, especially around hardware setup, flashing instructions and ideas for new interactions.
