I didn't quite pick up all the debris, but I got the King Fish and it seemed like there was only repeatable things left.
You guys did some really, really great work! The reeling in animation was amazeballs. The music was really nice and fun, especially the sound you use when you lose the fish. The pastel colors and design of the cute fish you find and the bird are really cute! I love the descriptions of the items you find too "Y'arrrr!" very funny. My absolutely favorite concept is the fact that the surroundings change when you reel in a new item. This by far was my favorite thing in the whole game.
Since that was my favorite, you can probably guess what I'll suggest to improve upon your next project in the future! That concept of the environment changing with the items you reel in was by far the #1 thing that kept me playing as long as I did. For future projects, I'd recommend focusing your time even more on that. Ideally, if you have repeat items like you did here, I wish that each plank would slowly make a plank path, rather than them showing up all at once. It'd be really cool if you could see the fish you catch over time in your bucket (maybe the option to open it?). Maybe multiple tyres means you eventually pile up a tire fort that looks like a bird or something. Maybe multiple unicycles means you also fish out some duct tape and make a proper bike out of it. I think players really really enjoy seeing improvements over time, so I hope this gives you some inspiration for the future!
Other things I saw that could use some more improvement on your next projects: The kingfisher default pose when not walking is just his left arm sticking up in the air. That seems really awkward and probably needs to be down in a neutral position if you don't have time to animate. The arrow that helps you know where the bobber drops doesn't work - there is no line that indicates where the collision will actually occur. If the bobber lands on the tip, let it land on the tip. If it lands on the first orange rectangle, do that. This might be a problem with the way you handled it - Was the arrow 3D and so incline was a problem? Might have needed to switch to a simple flat red line that stretches over the water and isn't connected directly to the pole. Another frustration was landing your bobber perfectly on a black spot and then it immediately failing. You don't get a "fail" sound, either, it just disappears and you have to try again. Why does it suddenly disappear? Final frustrating thing is that if you send your bobber out to a far away spot, sometimes as you start to real in you just get the "fail" sound and it disappears. I don't see a red rod line to indicate that you've been tugging on too hard. It's slightly pink and then you "fail." You might need to do more playtesting to get the right results you want for this kind of thing.
Thank you so so much for putting in so much time and effort! This is probably one of my favorite submissions here on the website. It's relaxing and clever and made me smile. Wonderful job. :)
