Really lovely music and artwork. It always comes as a disappointment when one notices that their game jam concept is too ambitious, but what resulted here was nicely polished and works well as a teaser. I found it an intriguing choice to use this kind of medium to discuss such "heavy" topics. It is of course not unusual to use fiction to explore serious, real-world subjects, but in smut it's much more uncommon. And the serious subjects wove well into the more explicitly erotic sequences, which themselves have a good flow and ebb.
I do have one complaint about the writing--much of it felt very insubstantial. I felt like I could have accidentally clicked through 20% of the dialog and would not have missed anything. That sometimes makes it hard to tell what's important. Clover and Hazel spend a good amount of time discussing the mechanical details of their in-universe novel, but that didn't go anywhere. Having a whole scene to introduce Charlie probably makes sense for the multi-episode arc you're trying to tell, but it felt too long for just this prologue. Fluffy dialog is certainly naturalistic, but in fiction, reality is often condensed for easier digestion--I have the feeling "hyper-realism" is not your goal here. Then again, maybe I haven't read enough visual novels, and this is typical for the genre.
I liked Herb. I wish I could have my own Herb.
