Wow, very good level graphics and ambient atmosphere here!
Although it ran extremely slowly on my laptop, I felt the idea and execution were spot on, so well done there!
The quality of the music was good but I would have wished something more in line with the water theme, slower and more dreamy/wavy.
If you do create DLCs for this, please write some details regarding that in your game page description, I would be interested to see what you would add in.
