So I finally got to playing the second game in the series, and I got to say, it's both better and worse than the original in a couple ways.
Your art has improved from the first one, that's an obvious plus, but this game was definitely shorter and more linear than the other. While it's good that you no longer have to pixel hunt to find all the objects, it kinda removes the old charm the first game had with feeling like you gained something from finding some randomly hidden object.
The story is about as silly as the first, this time around you're hunting some legend of diamonds, which wasn't bad, but a little generic. There was a minigame that was half-baked toward the end, needed some fine tuning on hitting the keys for the sharks. It wasn't all that difficult though.
I wish there was an actual bad ending if you accepted the fairy's deal, instead you just have to backtrack a little.
Overall, a little worse than the first one in my opinion, as the game felt rather empty at some points, but was still pretty fun to go through.
