that idea sounds pretty good CC
but the way I see it would save them even more trouble. Who said the main character has to swim underwater? All I'm looking for is the ability to swim across the water, just like regular swimming, I wouldn't even mind if if it didn't have the option to dive underwater...
That option right there would still save you from all of the annoying deaths, and accidents, I mean if you think about it it's kinda pointless to actually go underwater anyway, there's nothing to do
