Haha the sounds in this are horrifying! Was not expecting those fish wails. Short and simple experience, I enjoyed playing, was slightly surreal between the sounds and the aggression of the whale(?) movements. Victory screen was fun!
For the UI elements, I would suggest either putting a slightly transparent panel under the text, or positioning them so they are over "clear" areas (such as the sky in the top half of screen). Should improve the readability, and maybe give a slightly cleaner look.
Have a restart button on the end screen! Don't force me to quit if I want to play again.
Not sure if it is possible, but if your able to export the project as a web build in unity, should allow for more people to play.
Great work! had a fun time playing through it!
