Excellent excellent excellent excellent. The first time I played through I did it with the mind of a gamer - don't do the stupid things like take the lower, more difficult path, and don't jump into the spikes. The progression of the game confused me and I almost stopped playing, until someone in the comments told me to continue, but go along with what it says. The second time around, I realised how beautifully the voice works as a God figure, and how different the plot becomes. In the care of The Voice, I had no problem clicking "girl" at the end of the game. That's what it told me to be. Excellently, excellently done.
The music is the default that comes with RPG Maker MV. But, you are right, they are similar. :D
