Alright, here's the deal.
I got so aggravated while playing your game I honestly almost rage-quit like 4 times. The biggest thing that got to me was that the piranha would swim in directs that were pointed no where near my mouse. It just really bugged me also when the piranhas would get stuck on the top left corner of the map for a few jumps and I got eaten by sharks a lot when I was stuck up in that glitch.
