The game is fine so far but it could really do without the voice audio files. I actually believe it would be an improvement to remove them or keep them to an absolute minimum.
There were several instances in which I noticed characters saying things but with an audio that said something completely different or even contraditory to what they were saying. Not everything but the examples I can think of from the top of my head are a woman saying "Come on in" (to a house) while the audio file said "Thank you", a girl saying "Who is it that you have your eyes on?" while the audio file said "Why? Why? Why?", a girl saying "Yeah" while the audio file said "No".
And this one is its own case, I think, when I encountered a character sleeping in class and for some reason he had an audio file from Nichijou, an already existing anime, of Yuuko (Nichijou protagonist) counting sheep while asleep.
Not to mention differences in range and energy. The characters are given so many obviously different voices that it's almost comical. The protagonist sounds like a 10-year old girl in one moment and like a 30-year old grown woman in another. Then scenes like one when a teacher punishes the protagonist for using her phone during class, her classmates laugh at her but the audio file used for them laughing very obviously sounds like much younger children. Or when the protagonist says to Nanashi something like "Fine! I'll go with you!" (to a haunted spot) in a "friend-angry", grumpy way but the audio file used for that sounds way too angry.
And this one isn't related to audio but it's something you can't help but notice which is (Slight SPOILER ahead) when Nanashi shows a picture of him with his mother and the picture shows a woman with a child who looks to be about 6-years old and he says "This was taken two years ago", even though Nanashi very clearly looks like he's around 16-years old, or 17." You can't help but think "You were that little 2 years ago?" (End of SPOILER)
Please don't think I'm trying to slander the game though. I actually like this game, I think it's fun and entertaining to play and I'm interested in the story so far.
