It’s a good VN, with an interesting concept and formula, and it definitely kept me hooked, once I got through the early chapters.
I still find it too wordy in places, it likes to repeat itself a lot, and some of the plotpoints move a tad too slow, even after being firmly established.
But yeah, cool art direction, nice writing.
However I have to say, I do not think that the music here is universally good.
One thing in particular is that you really should think twice before putting vocal songs in your VN, even if the language is gibberish. Those songs consistently distracted me from reading an otherwise fun part.
And generally, the music can be hit or miss, considering the VN and genre choices. Like, the composer definitely felt more comfortable with mellow piano pieces (I heard that Clair de lune reference!), than… whatever the hell was the music in chapter 3.
Anyway, I had fun.
