Oh wow, you did a playthrough!? OMG, Bullhead thank you so much! <3
I will definitely be watching it this weekend.
And yeah as for the limited VO, hmmm, I wonder if it's just a case of the VA's performances that made it feel off, or if it's just the concept of this kind of VO happening in a *horror* VN? I know in more typical VN's (otome, dating sims) it usually works, but perhaps for horror VN's it's not quite so effective.
