There is a credits screen within BaDIK, but it's only displayed at the end of the game.

As others have mentioned, the voice work isn't credited in current releases.
All the voices (so far just Jill and Bella but they were canned) are done by VoiceLikeCandy. Everything except the 2D art, some play testing, and discord moderation is done by DPC.
Yep, there is Jill intro (technically open cutscene) as soon you boot up new game, such gorgeous amazing voice has Jill

. Although I can imagine picture their voices in my head when reading dialogues, not that uncommon

I'm unsure whatever was the reason to discontinue voiceover lines feature, I sincerely hope DPC would consider add eventually near future being implemented if up to it. Thanks for pointing out, guys
This fan render is close to the truth, most likely it will be so. Its so realistic that I thought about another preview from the DPC
As much I love this render to happen, it's high unlikely although I mean no criticism and with humor. Reminder that I find Jill's personality has some sort of being high protective over relationship with Bella and infidelity would play such unique role with MC. In this case, from my perspective of view resolve she either to come up to be convinced with some explanation logical constructive reason as to what happened that day (assume that what she saw) along together with MC & Bella or ditch him (BIG DIK Move tbh) which comes with actions that would have later consequences as we move up towards branch, women rights protest and turnover? Revenge which might hurt someone?
As much I want to see an happy ending to couple, it's high likely to have threesome together with Jill & Bella
