I really like the aesthetic, and I love the concept of using the radar for a find and rescue mission.
However, I was initially surprised that the intro talks about an aberration on the radar, but then you can't actually witness such an aberration in gameplay. Then when replaying I realized that the fishes do show up on the radar when angered. However, at that point, I don't want to look at the radar because I want to run away fast!
I think it would be interesting to have the player witness that something is abnormal by themselves before being put in a dangerous situation.
