Jolly Roger's Lagoon was fine and beautiful, but it felt too big and cumbersome. Mostly because the swimming mechanics weren't the best. Swimming itself was okay, but the inability to attack was what got me. Yeah, you could shoot eggs, but you had to stop, orient yourself, aim, and...oh great, the baddie was BEHIND you. I felt like I couldn't appreciate the design or mystery of Atlantis because I was always worried about those darn puffer fishes coming out of nowhere. So I just kind of hid in places they couldn't reach until I decided where I wanted to go, and swam like hell. Not very fun.
Make swimming fast and fluid, and give us the ability to attack on the fly, just like on land. The transition between land platforming and swimming is perfect in Rayman Origins. You still move just as fast, and can whack stuff. Something like that, only adapted to 3D.
