Update script.js

Ok, this is a little over my head, im still a noob, but here is my try ... 
Idea is when fish has been caught, to start timeChek(), which starts new function fishChek(). 
After fishChek() being accessed second time it should remove fish from inv , and give message that fish had gone bad.
I was not able to make it run after 6 turns(timeCount) , sorey Gabriel .
