Calling out the Jenis Academy stretch would be bold in the fandom, lol. I mostly agree with you though, I think that whole chapter was a low point for the series.
Sky SC in particular has some brutal pacing, so it’d be reassuring for the future remake if they shuffled up this game a bit.
They were that style of sprite derived from prerendered 3D art that was popular in the late 90’s/early 2000’s.
It’s unfortunately looking like ports of this game are going to come later.
