In the second level it felt a little unforgiving since you had to stay so close to the group, so I ended up evading the angler fish by swimming in a circle.
The third level felt just right though, and I was able to evade the hunter by blending in nearly the whole time. And I noticed that the hunter is faster than you, which makes the “running in circles” strategy much harder, but I found it was still possible if you run diagonally. Wasn’t sure if that was intentional or not.
But this was a really solid mechanic and a good take on the theme!
