You're encouraged to use the whole day to experiment with bait & fish combinations, even if you catch all 3 early.
Also; keep an eye out for Granny to give you hints! She'll give you 2-3 hints a day, usually.
I will concede that hooking the fish is kind of inconsistent and hard to feel out, so if I continue to support this game I'll probably tweak the minimum hook distance.
Thanks for your input!
