Good for a relaxing game
simple game play design is what you set out to do and you accomplished it. i really enjoyed the music, in fact so much that i just sat at the title screen for a bit just to listen to the music before i started playing and it really suits the marine life theme. I guess for me i appreciate what people come up with as long as its playable. I know that this is one of your first submissions from a while back but i feel like giving advice. you don't have to take me seriously cause i know nothing about designing a game (though i would like to try but i don't have the right equipment)
I feel that a bit more of a variety in scenery, marine life, and a multitude of relaxing songs in different forms would have really pushed it. I actually don't mind the soft graphics cause it matches with the stress reliever theme you got going on. Here i go on to the rest of your games.
