Hi, I am the owner of the fishbitfish.com game. I just want to note that creators of this game have stolen our idea, our client-side scripts and our texts. 
your idea was nice and you was the first ! but competition exist in every market.
Yahoo.com made first search engine but google.com is best search engine in these days. so google steal search engine from yahoo?! I am not agree.
You develop your script on php, sql, we develop it on .net mvc ! you just accept bitcoin, we accept multiple payments, you don't offer registration, we offer registration.
Finally, Our game strategy is same and I respect you for creation this idea.
Good Luck
