Glad to hear you're having fun with the games! :D <3
Version 0.3 of Poetry in Purgatory is planned for release later this year and it will be the biggest update yet (it will include Act 2 of the main story as well as two new routes and several side stories, along with new music, characters, BGs/CGs, achievements etc).
We're currently finishing up Ezrebeth (Definitive Edition) for its March release but after that it's right back to Poetry. :)
