I played this and it left me cold. I'm not sure to what degree this was work from the developers or a mix of pre-made assets and a transcript from a real legend? As someone not familiar with the source material, the adaptation was not particularly fun.
The initial art was nice, but suddenly very awkward bits (especially related to the horses) appear, which make me think the cool art is an asset from somewhere, which somewhat diminished the praise.
The story, as I understand, is from a real legend? That part is perfectly fine, but for a visual novel it does not do a good job of conveying it in an interesting way. Mainly it was a chore, and there were WAY too many references to names and objects. The writing style (I could be wrong) feels strange, as if it's lifting lines from the legend as is. It's just not entertaining to read.
There are also multiple errors on the display of assets (especially after the flashback).
In summary, this was not engaging or entertaining for me.
