Keiichi123, the water looks okay as along as it uses "Water" combos and not "Shallow Water" combos. I'm not sure if Link should be able to swim over the bushes and rocks (if the flippers are included in the quest, that is). Also, if there's bushes and rocks down there, it makes me think that maybe the water level will be lower later in the game(?).
The water is "Water". And yeah, the bushes are kinda out of place, I'll have to get rid of them. And no, you don't lower the water level. That'd be kinda silly in this area But thanks for the Criticism!
