I caught a Mahi-Mahi and now I'm craving seafood xD. Nice work on the visuals & audio and setting the mood. One thing I think it could use is a little feedback on the cast, like a little splash effect for the line going into the water (that way you don't have to do a full fishing rod/animation :)).
I was a little thrown by the circle/clicking at first because I didn't realize you could wait and read it, so I sort of panic-clicked the first few times and was not able to read the text LOL. But once I read it, I became a wealthy angler!
