Cool and very unique concept. This is what a VN should be: not just a written story / novel supported by visuals to help imagery, but a story that also utilizes audio-visual aspects as the storytelling device.
It has the potential to be an excellent short horror VN. Taking away the visuals really sets in the feel of the story, though I'd argue using really blurred out background would better fit the title. The joyful look of the main menu works well to strengthen the eerie vibe, made me think about Midsommar tbh. I only have a small grievance about it: some elements don't contrast well, which makes them hard to read (unless you did that on purpose).
Unfortunately, aside from suffering from being undercooked, it missed the opportunity to lean way harder into audio. Making us "blind" will force us to focus on other senses. The chimes and the "chase" scenes were great, but it could use way more. After all, nothing is really silent; there is always ambient sound. Even the silence/absence of sound, at times, can be used to build up unsettling / "something is wrong" vibe.
Nothing that can't be fixed, though. Great work!
Cheers!
