Thanks! Here's an update:
The fishermen now lie in wait at the sides and ensnare you with their hooks when you collide with them.
Now the idea is the longer you leave them clinging, the more the capture meter fills. When the capture meter is full, then it's game over. Also, the more fishermen clinging at you, the faster the capture meter fills.
So the idea is to fly high then dive hard, crash on the water surface to shrug them away.
Right now it's very easy to fly and dive, but I'm going to add some challenge to it, most likely changing the controls a bit. That was really the plan though; the jump controls right now is a placeholder so I could get the buoyancy just right.
Some random thoughts:
* Bullet time ability?
* Dolphin enemy, pretty much the same as the fisherman, just different graphics. Instead of a fishing pole, it swallows you, but you'll still be swimming while you're in its stomach. Instead of a capture meter you have a digestion meter but pretty much the same thing.
* One boss is a navy blockade, wherein you need to fly high beforehand and crash as powerful as you can, and make sure to land right at the blockade to destroy it, freeing your fellow fishies. Bullet time ability will probably be useful here. (Will probably need a mini-map)
