Great start for a game!
I got to 162 before I accidently fell off.
You might want to add a system for restarting or recovering from falling off. Other than that, it looks good, keep up the development.
The game is utter chaos and it was fun.
My best score was 47
As Brett said the ability to restart the game would be nice (I played several times)
What would also be a nice improvement would either be a UI to tell you how many hearts/fish you collected, or some feed back as you successfully collect them (sound effects or exploding partials?)
