Yeah, I agree with you on that :3 I would absolutely love to have been able to do more with this. Sadly, because this was made for a game jam, I was veeeery tight on time for submitting it. If I'm remembering correctly, I was working right up to the deadline to get it done, spending like 15 hours a day on it during the last week, haha.
The wonderful voice actors who helped out on this project are friends + friends of a friend who lent their time and talent specifically because it was for a jam, so it would be unfair for me to ask them to record additional lines for new content. Sadly, I'm perma-poor >.< Otherwise, I'd happily remake the game in the new engine that I'm working with now and pay them all to record additional content.
Of course, there's always the option of having new content which isn't voiced, but I feel like it just wouldn't be the same with this playing out more like an audio drama type thing than a typical visual novel!
Anyhow, thank you so much for taking the time to play + comment :3 It's much appreciated!
