I worked around the bugs I found in your script (reported them in your DM ^^) -- but this is a solid short novel! I enjoyed the atmosphere and the deep sense of reflection that Ina had on this particular Halloween night.
(spoilers below)
I actually felt quite a bit of empathy, like I understood why Ina was feeling "blah" about the specialness of Halloween. There really is a specific vibe to the season's end and the festivities that follow, that can sometimes get "lost to the wind" so to speak. Being in that state and seeing it around you, and subsequently feeling disconnected from that special circumstance (especially from your friends) can be isolating, and certainly induce some reflection about it (clever!). Can say I've been there... but being able to see what the festivities represent -- to induce a spark of excitement and change of pace, if even for a moment, in an otherwise-mundane or perpetual cycle of daily life -- is what makes it a special occasion. Even if the occasion itself comes year after year!
As for the actual substance and story flow of the novel, I thought the dialogue was witty and pretty robust! For context, I read all text out loud with what I perceived to be their intended inflection. I enjoyed the visual flairs and the distinct font effects, and I really appreciate Jonter's direction with the artwork (very tasteful!). The references were cute and sly, too... and those riddles, hoo boy!
In a couple of parts however, I felt like the pacing of Ina's thoughts, and also some of the transitioning dialogues, was a little off or abrupt (including just a bit the very end), and some dialogues could be split into different lines for better pacing -- but it didn't too significantly disrupt the flow of the narrative. I do feel like the high-level tracking of Ina's reflections on Halloween was a tad tricky to follow as a result, but I also feel like I did reach the end of the rollercoaster and the intended conclusion you set up pretty steadily (bearing in mind I'm a seasoned VN reader).
I did enjoy seeing Ina bounce off of her fellow Myth members, and feel like they did increasingly contribute to that underlying pace as they were introduced -- but Kiara by and far was the most impactful character to following Ina's headspace progression, by a huge margin.
--- In all, this was good! I would've loved to read more✨
