Great storytelling game , I loved the whole experience , it felt immersive. The art was cute as well, the hand drawn-like whale was a very good choice. Clever combination of 2D and 3D assets as well.
As per feedback, the camera following the player could be a bit tighter, so you don't end up pushing to the side of the screen (as camera moving together with the input and not just when the player is further to the side of the screen).
Sonar VFX was very pleasant ,but i didn't understand what it does.
Great job you all!
