Thanks a lot for playing and for taking the time to write this up, this is exactly the kind of feedback I was hoping for.
You're right that once harvest power and multi harvest are up, clicking stops mattering and you can just drift down and vacuum everything in. Your small / medium / heavy idea is a really clean way to fix that. Depth-specific targets and weirder finds like wrecks and sea creatures are on my wishlist too, the deep sea deserves more surprises than it has right now.
On vision: the Sonar Array upgrades do widen your view a bit, but I agree there's not much worth searching for yet, so moving around doesn't pay off. That ties right into your other points. This is going straight into my notes for the next update. Thanks again!
