Progress so far:
Character Controller: Land and Water locomotion, with swimming!
An inventory system: for collecting things.. like keys or resources, like oxygen tanks.
Underwater post processing, because... ambiance is where it's at!
Music: and underwater sounds for deeper ambiance.
FISH! :the fish are kind of my pride and joy right now. They swim in pods. If they see each other, they'll group up, designate a leader, and follow it. Sometimes they will separate from the leader and act independently. They are mostly just an aesthetic stroke in the environment, but to make the underwater feel alive.. I think it's important.. and don't mind me if I come up with an excuse to make a fish randomly turn into something else and jump scare you when your oxygen gets low and you start to hallucinate. 

Here is a short video showcasing the progress this all in action.
