So glad to hear you had fun with it :3 Especially since this project seems to get a lot of negative ratings >.< even though it's a fan visual novelisation, people keep leaving mean reviews about the characters and story sucking... which isn't even my fault, cos I just localised it xD
Anyways, to answer your question/s (and I can only apologise that it's not a very clear answer >.<)
I certainly hope to release vol 03 someday, but, unfortunately, I couldn't say exactly when that might be >.<
This year in general has kinda been a disaster both with my physical and mental health. I'm just starting to come out of it now, but at the end of last year, I went into the most severe autistic burnout of my life so far, which lasted about 11 months :(
My plan for 2025 was to finish and release the full version of Lovestarved, a project I started and released a demo for during otome/josei jam back in August 2024.
But so far this year, I haven't been able to write a single line of code T_T So I'm very behind my own schedule atm.
Because my Yandere Heaven fan game is a side project, it's pretty low priority, so I have no intention of doing any work on it at all until I've at least completed Lovestarved.
Once Lovestarved is finished, I haven't 100% decided yet what I'll focus on next.
So while I do intend to work on Yandere Heaven vol 03 at some point in the future, right now, I have no idea when that might end up being x3
I think vol 03 was actually my least favourite episode of the drama CDs as well, haha. Doesn't mean I'll skip it, cos that would feel wrong.
I’m sorry that’s a super unhelpful answer >.<
If you’re eager to experience it, though, I’m pretty sure there are already some rough translations of volume 03 out there somewhere online, and you can usually also find the original Japanese tracks themselves somewhere too if you can’t find the CDs to purchase anymore :3
