I only played part of Jewels of the Oracle (see below), but yes, I believe that Quest for Karma is very similar, being basically just one puzzle after another. I'm sorry you weren't aware of that before you purchased them.
If you will permit me to meander down memory lane a bit, what I am amused now to recall is how poorly Jewels of the Oracle ran on my machine when I purchased it shortly after its release; the jewels took forever to fall during the intro screen, and I remember thinking it was time to get a new computer.
