I know there is going to be underwater caves, but how long are they to get through.
Also I thought, would it be a good idea, where we can swim into a cave underwater and it's like a pool. We climb out in a pocket of air and walk through the cave, climb parts and just walk through with a light and maybe find easter egg inside the cave, like a troll in there or a house or treasure for money etc.
It would be cool if we could find caves where we come up from below and be able to walk around inside and making them massive to explore.
If you get my meaning?
