To put it nicely, this stage is going to take some getting used to.
To not put it nicely, it's chaos.
Low tide is pretty simple with two very large bits of land to fight on.
Mid tide is okay. It's a little cramped, but you can get things done.
High tide is a nightmare. Remember the platforms in Mariner's Bay you took where no-one bothered to wait on you? Imagine that being your only form of getting from one part of the stage to the other. Also imagine someone not waiting on you getting you killed as you try to get on the ramp. It hasn't happened to me yet, but I can guarantee that it will. Also having to take those things to get eggs. I'm almost wondering if it's just not worth going to the other side unless there's a stinger, flyfish, or drizzler.
The only special wave I encountered so far is the Mothership. I'm still not sure on the best way to approach it, but once again, having to take those platforms makes it needlessly tedious.
E-Liter is king on this map. You can snipe everything from right beside the basket.
