Spoilers follow. Reader beware.
Theme: I don't know if I saw it.... barring the good ending death of his heart being too large.
Story: It felt like a forced romance, but that diegetically makes sense because the silver bullet is real and supernatural evidently. I got only the good and bad endings, and didn't try for the third. The dying seems kind of out of pocket for the narrative, especially the canibalismish ending unless the explanation is supposed to be that the silver bullet is so potent, but then why is he more willing to go to killing rather than... compromising on his values a little? My man gets upset if you don't love the same books he does. He's inflexible in the slightest?
I do like the conceit of being forced together due to the weather (classic trope), but this strange supernatural force as a metaphor for his heart condition or something is bewildering to me.
I think too much time was spent on minutia (and aough, the start with the wakeup) in the story, and we could have had more beats to develop this relationship. Maybe even the bar scene the prior night. The drink doesn't have to be mentioned until after. Could just have a sign with the menu saying it's on it.

Story Aside: Sweetie, I am dying that you had them reading FVNs in universe as books, although I take umbrage at the sort of what felt like your real life PoV criticism for why people not liking what you did was bad. There are real reasons to have issues with all three of those works, and it's a thought terminating cliche to just be like "they didn't understand the complexities". Unless the wolf is supposed to come off as less likable as opposed to being your mouthpiece."

Presentation: I appreciate your regular and repeated use of SFX. I didn't love the periodic silences that felt out of place.
I also liked that you had a developer title screen. Pop off, King.
I think the attack was well sequenced, and your characters were cute. Well done for the minimal game jam time.
My main thing is that your warning screen passed too quickly. You couldn't roll back, and it was a LOT of words for like 5 seconds. I read fast, but not that fast if I'm trying to be prescient of concerns.
Creativity: I'm kinda mixed here. Romcom trapped trope? Of course. Magic drink that binds? Kinda. Going feral from it to cannibalism? What?? Excuse em? Heart condition that masquerades as a supernatural force to hold someone from doing things that could hurt them?
Strange, but the issue might have been just not enough build up to it. With more time to prepare, these would have pulled off further.
Overall thoughts: I think you did a good job overall, but your focus on the narrative was out of place commiserate to your ending. You needed to remove some of the breakfast romance earning points and wakeup, and perhaps have more of the night before to show why he would even be invited over, Silver Bullet drink aside. Also need more definition for the why of the supernatural, because I don't think it being like a manifestation of the panic attack is a good explanation either.
