So I entered aquacave through the river entrance. After about an hour I got up to the high waterfall bit and was unsure about whether to continue or not because I didn't know if there was an exit there or not, otherwise I would get stuck in due to tides. I've also read something about a manhole but I'd prefer to use the water entrance because for me it would be easier. Does the waterfall bit lead to anywhere? Is there an exit anywhere that's not tidal?
Exploration is an addiction.
