Alright! Here's a game I played a long time ago:

   

I'll guess Ring: Legend of the Niebelungen just because there are some strange-looking characters in the screenshots I've seen.

That's the one!

The puzzles are equally strange. This game took the concept of a space opera to a whole different level.

Interesting decor:
   

And Then There Were None?

No, although the amount of murders in this game could be the same.
   

9: The Last Resort? Which I once purchased at KB Toys for .99!

No, 9 is a much more colorful game.

Maybe the food did everone in:
   

The first screenshot strongly reminds me of The Final Cut.

It is The Final Cut, Kamineko!
