They are definitely sprites made from some former 3d model klonoa lephise and some others also have that weird look about them when you run a ps1 game at a high resolution.

2xsai textures and some texture filtering which I never use because I hate what it does to sprites but I took a screen for comparison.

I'm derailing the topic a bit sorry I get a little crazy when I want to test and compare things about a game I like to this degree.
I'm going to try to resist posting anymore before I got on a spree of detail searching.
Maybe I'll make up for it later by trying to get info or least comparison screenshots on the King of Sorrow.
I'll have to re beat klonoa 2 again though
lost my save data on that game a while back. Kingdom Of Sorrow and The Forgotten Path are gonna be hell
