This was a lot of fun. Great little jam game. Congrats on finishing and submitting!
The core loop is very simple yet satisfying. Fetch quests aren't terrible when they're this straight-forward and quick! The sfx and music really stand out here. The goofy little voices and drowning sound are light enough to offset the fact that you're kidnapping and drowning people. The music gives everything a bit of a whimsical vibe that matches super well.
The biggest areas of improvement, for me, would be the camera and the obstacles. The camera felt a little too close such that moving down felt awkward and slow, while moving up felt great. Pulling the camera out a bit more would give the player more opportunity to react to those foreground objects and making finding your target a bit more manageable. The obstacles were mostly fine, but I didn't realize the coral could also detach grabbed guests. I don't know if this is because they didn't stand out enough, or if my brain thinks of coral as "underwater only", or both. Once I realized they were knocking away my hooks, it made more sense though.
Congrats team. You all made a super cool little game. Well done!
