Still very surprised you liked it this much. I thought you would like it but a 10/10 never would have imagined you would like it this much. VERY VERY glad to see, probably your best review so far imo.
Not sure if you know but one of the reasons why Higurashi Kai has better music is because since Ryukishi was just middle class with Ni he actually could only use only free non copyright music online. (The only people who also worked on Ni were his brother, himself, and his mother and father did advertising). Most stores wouldnt even carry his game because he was a nobody. But once Ni became popular after it spread online then it started selling very well so he was able to spend more money on Kai.
Edit- Forgot to add which lead to Kai's success and then when Umineko was released at C72 it sold out in 30 minutes because Ryukishi would never have imagined it would be that popular.
Also needed to add that the music in Kai was done by fans of Ryukishi who sent him music, Dai being the most influential as most of his music is in the game.
