Hello, I checked out your suggestion! In terms of "a game that benefits from a mod like this" I get where you're coming from! A Shot in the Dark seems to like its branching narrative, though it feels like this tapers off quite a bit in later chapters.
Now, creating a mod for any game is a sizeable commitment and I'm very picky when it comes to my modding candidates! So far, I wouldn't consider ASITD amazing enough to become a candidate. It's good but a few things hold it back: The story pacing feels off; sometimes we make no progress for a while and suddenly we have a lot of progress in a short time. Then, I don't really like how the lewds are stuctured, but I understand that this is prbly due to Daz's limitations. Finally, I think that 10 LIs is quite a lot and I struggle to really connect with the LIs in a meaningful way.
I liked that the game had interesting ideas both for the story and the lewds, and the visuals were great too. I'll keep playing future updates of it, but the game doesn't meet my high standards yet. Still, I'm thankful for your suggestion, I definitely don't regret giving this game a shot!
