A pretty good read! The presentation is admirably polished – the UI is stylish (I could lose the texture behind the text box, though), and there are plenty of nice audiovisual choices that underscore the horror moments effectively. One thing I'm not quite sure about: does the art style lean too far towards cartoony & cutesy to really work with the genre? This kind of juxtaposition can feel purposeful, but I fear how the characters are drawn is just kind of inherently silly, making the goriest image in Silverstone: The Morning After fall flat. Also, while I shouldn't be mistaken for a music critic, a lot of the songs sounded, for a lack of better term, a little "default presets"-esque.
The VN gets a lot of mileage out of its nonlinear structure. I like how it recontextualizes various details across the routes. Though this may just amount to personal preference, I thought there were a lot of choices, however, especially since most of them served the same function of deciding what ending you were heading towards. The story did not feel difficult to navigate – getting all three endings was straightforward – but more could perhaps have been done to experiment with the mechanic.
As for the prose: smooth to read, largely without the kinds of polish issues characteristic to game jam projects; the horror scenes in particular were full of atmosphere. My feelings about the character drama are more complicated. I think the post-credits scene for one of the routes, where the story goes into retrospective mode, felt like the most affective moment in that regard – the main story itself is so sudden and limited in scope that it's hard for it to hit emotionally. I felt like there was not enough outside context to really hone in the impact of this one night for both parties and really sell its narrative importance.
Also, there's nothing wrong with wearing one's influences on one's sleeve, but referencing Echo while also replicating its central horror elements – a small town known as a hotspot of paranormal activity, a mysterious voice haunting the protagonist via the narration – felt kind of jarring. Maybe it's just that with the setting not getting a lot of description and all the questions remaining without answers, the game simply had no opportunity to set itself apart yet. Still, it doesn't necessarily make for the most thrilling intro to the larger project lore-wise.
While all elements may not play together perfectly well, the amount of work put into the game is impressive, and it has fantastic moments of horror. Looking forward to more, especially if it keeps those strengths while also becoming a little more precise and purposeful in its literary intentions.
