I currently use the Ren'Py discord for help with Python so your help is welcomed! Grogplongk is writing scenarios as we go, we get occasional contributions by anons that come in and provide scenes (like an early Lyra route that looks charming to write for) and I'm trying to connect the pieces together chronologically.
Here's some current stuff that needs to be written:
Pinkie Pie talks about cooking with Anon at the party
Rarity talks to Anon about clothing and what he'd like to wear and she's intrigued.
Celestia and Luna show up fashionably late and bicker a bit before talking to Anon casually.
Day 1 ends and Anon can choose where to stay or default is Applejack's farm.
