The first part where the fish looks for food I put the fish at the very top because I know that the trash spawn 'Y' coordinate may not go all way to the top, and I was right, it didn't. So, I just sat that and I never saw 1 fish I could eat, so I died.
The Fisherman should have a target to cast to. Not one fish got close enough for me to hook. I never did the 3rd part.
Fishing games are usually great fun, you just need some work on yours. Keep at it!
