Hmmm...interesting. I heard somewhere that the game was made with a lowered budget...perhaps they originally meant to make them cel-shaded, but didn't, due to budget issues? Or maybe it was rushed? I dunno...I mean, Cel-shading is just a texture edit, it's just a layering over the graphic...if there were a "server crash" , then they'd also lose basic textures...or...stuff. I don't think it has anything to do with a server crash. (Also, there's the issue with the fact that several models from this game weren't in Klonoa 2 to be reused in the first place. Okay, I'm done over-analyzing.) Maybe they thought at the last second that it shouldn't be cel-shaded, and that it might look better as is? (Don't forget, that wasn't the only design choice they made. I guess they thought people would react similairly to That Klonoa redesign they made for this game...which they scrapped almost immediately, due to fan response.) Honestly, we'll never know, unless someone asks them at a convention, or something.
