I enjoyed the swimming animations quite a lot. It had me a bit confused for a while because I didn’t understand why a fish would give me a “quest” to talk to another fish. But once I figured that it was quite easy sailing (except when I forgot to breathe, multiple times)
The underwater shader / visual effects was really nice, but the UI could have done with some outlines as they melted into the background/water colors.
I also found the edge of the world!
