I really love the visuals of your game! The sunset and water looks super nice and they both work together very well. The fishing was real smooth and simple, which I enjoyed. I like the oxygen level for whenever the player is submerged in the water and the map is big enough to explore.
I think there could have been some sort of quest system to incentivize the player to go out and catch fish and explore. A death screen would be nice to let the player know the Sherk has killed them, as well as maybe having the Sherk patrol the region.
Overall this is a nice base for a 3d fishing horror experience. Nice Work!
