I really like how you incorporate the baby dolphin's characteristic into your own game play, like how you need to go to the surface of the water to get air but you still want to swim underwater because you have a higher speed in the water. This is really a good moving mechanic. I also like how you are able you swim with your family when you reunited with them. One suggestion is that the map do seems to be a little bit too big to find something in it, and I often get lost with the sence of direction. I do agree with the Finn's comment that adding some landmarks would be make this better. Also I think maybe you can let the other dolphins scatter around the map, so you can find them one at a time and there's more chance that you can meet at least one of them. It is kind of furstrating if you swim in the water alone for too long, but it's also okay if that lonelyness is also your approach. Other than that, really good game and I like it a lot!
