Definitely a solid update, much more fun to play now.
A few issues I've seen are golden fish spawning too close to whirlpools or the bottom. As for heart eggs, there's been a few times where they spawned ahead of a whirlpool causing it to be missed.
Shark hitbox is still janky af and there are plenty of times that the shark warning has only worked on the left side. The eel really only seems to be useful in very niche circumstances, but an interesting idea.
Keep up the good work!
