Nice music, satisfying sounds when you click on the fish, and I also like the way the end screen fades in and animates. It is cool that you are getting deeper and deeper and you see the sea get darker. I wish there were more challenge as you get deeper - more/bigger fish perhaps? It could get really frantic once you get really deep where you get to the point where you almost cannot click fast enough, and that would really separate the highest skill players from each other. Also might be fun for the score to be in a unit like meters (or feet) so we feel like we're exploring the ocean. Great work though making the game, it does have a satisfying feel to it!
