" And on the other hand, the overworld is much easier to the point that anyone who liked how frantic NecroDancer is will probably find Cadence extremely easy."

Yep, I preferred Necrodancer over this (though I didn't go through all the classes I think I got the first few). It was fun to mess with but it could have been better. Maybe it has to do with the markets as you indicate. I'm sure that's part of it.
