I tried it, only beat 70 levels, stopped for some reason.
With Pokemon Rumble World, I played it, beat one level, can't stand to go back to it.
I'm legitimately considering buying that new Puzzles and Dragons: Super Mario Bros Edition. I liked the more RPG-like gameplay in the demo over Pokemon Shuffle and it's effectively 2 games for $30.
Also, no microtransactions!
Value.
