After playing every single route, and even replaying some of them, I can comfortably say that this is the best VN on this website. Period.
Characters are all loveable and likeable in their own ways, the artstyle of the characters is pleasant, and all the scenes look amazing. Additionally all characters are extremely well polished and likeable in their own sense.
Language is good, and the writing is beyond what most novels do. It's very well flowing and I enjoyed the little details where human body parts are replaced by their animal counterparts, i.e. hands-paws and so on.
Sound design is also phenomenal. The music is atmospheric and fits the scenes extremely well.
All in all, as I said, the best VN I have ever played. 5 stars and gimme that next Rune update.
