Very nice game! I just beat it, and have to say that it was a very nice departure from the recent Cursed Travels horror-puzzle series. My only issue is that sometimes, when I miss, it detects two missed inputs instead of only one. Other than that, wonderful little game you made here.
I also love the "New Game+-esque" Endless Mode feature after you catch all of the fish. It's relaxing to just fish and see how big of fish you can catch.
My highest was a 35.80cm Rainbow Trout. What's anyone else's biggest catch?
