I also got bored with Bayo 3. I did beat it, but man, it was a chore.
So many problems:
The performance on switch was horrible for this game.
Bayo's voice change made me feel like I was playing a different character.
The enemy designs were all same-y. I had trouble telling them apart sometimes.
Tedious puzzles, weird level design. Clunky combat (when controlling the demons or Viola).
The plot's a mess. Origins should have been released first to at least give some context to all the fairy based stuff that's going on.
Even with all that against it, the game is still a good game, and I'd re-play it on better hardware. It's just far below the other 2 IMO.
