This is cute!
I'd love a way to remove critters in case I get too many or they get stuck. 

And to see more colors if you are still working on this.
It's very relaxing to watch. 

I have the same problem. Running in Chrome on Mac os. 
Tried in FireFox, and only got a black screen. 

THANK YOU!!!
I didn't realize the signs said more things when you read them after!

Ok... So I've played all the puzzles I can find.  How do you get more fish power? 

Yeah, Mac is like that.  Here's how to open unverified apps.

Try to open it, then say never mind in the security popup. 
Then to to System Settings > Privacy & Security and scroll all the way down.
Under the Security section, just above File Vault, there should be a list of applications that you tried to open but couldn't verify.  Click on "Open Anyway" and say 'Open Anyway' on the popup. You will need to put in your name/password.

And it will run.  After this you will be able to open the application like normal. 

(Obligatory warning: Opening apps this way could leave you vulnerable to malware.)
