The People's Tree is an experiment in Asynchronous Networking and social interaction in Unity. Players design ornaments, write comments, and pin them to a single network-linked tree. You can view (approved) ornaments and the messages bundled inside. I'm overjoyed at the positivity and compassion seen from the players, and the variety of places they've come from.
Submissions go until 2021. Once everything is collected, I will get to work on a baked 'time capsule' version of the app!

It's a small experience, part of the Haunted PS1's Madvent Calendar, but I wanted to make sure this was available individually while submissions are open!
