It's okay—fun at first, but less fun the better you do. I made it to Day 102 before some kind of bug killed the game, leaving me unable to place the piece I held (or see the expected fish yields). I don't know if this would help you find the bug, but my daily income was listed as -1 for some reason even though I'd been making somewhere around a hundred net fish per day on the days before this.
(Wish I'd thought to take a screenshot.)

Specific criticisms:

1. Dragging and dropping isn't great; I'd rather click to pick up and click to place down. I accidentally "dropped" the pier at the place it spawned two or three times, and one of those times on Day 99 lead to a few days of weirdly changing village pieces before the aforementioned bug.
2. Speaking of which, the fact that new pieces spawn at the edge of the map and not *off* the map is really frustrating once your village gets big enough to approach or reach the edge of the map.
3. There isn't enough feedback about valid or invalid locations, especially with regards to those little circle ripple things that seem to block construction for some reason. I'd rather have parts of the pier turn red when they're over an obstruction than just have the piece not move when I try to drag it somewhere—it's nice to be able to blame your inability to perfectly place a pier on a specific rock rather than the game in abstract.
4. Having some indication that the pier piece isn't connected to other piers, or at least making it less eager to snap to such open space, would be nice.
5. If you're careful and check your options, it's easy to just keep biggering and biggering, your income and fish stocks just getting more and more ridiculous. I made it to Day 102 on my first game, with nearly a thousand fish in the "bank"; I expected to run out of space to put tetrominoes before I ever ran out of fish. The endgame was kinda hellish, with just finding a legal yet non-atrocious place to put tiles being difficult, and not in a fun-challenge kind of way (in part because of issues 1-3). I can't speak for people who went out of business in half the time, but I wonder if the game would have ended sooner if you didn't have a "fish bank" in the first place, if you lost when your income failed to cover expenses. (That would also avoid death spirals where your bank slowly dried up as you tried to avoid losing so many fish...if you covered up your fishing spots, I mean.)

Anyways, it's solid for a jam game, and you're probably not updating at this point, but I figured I'd give you feedback anyhow.

Awesome! Think I made it to day 40 something and then went bankrupt haha

A bit hard to understand at first, but that was really fun !

I like the feedbacks, and I love the art !

N E A T

Very neat to have the tutorial always ready for anyone who wants to reference it. The graphics were really great and simple and the sound effects were cute. I got parts without fisherman a little too many times though XD. None the less, the game is really polished. Great job man :)

Fun game and I liked the mechanics. I just couldn't tell if I was winning or not. Still had loads of fun with it though. Great work.

Wow incredible ! That is a very well polished game for 1 person ! Everything looks great and the gameplay is cool :D

The only thing that bothered me a bit is that the snap  won't allow you to place a piece exactly where you want, like it's stuck when there's a lot of things around ^^

But overall the game is incredible, very nice work here, good job ! :D

I cant believe only 1 person made this!! awesome bro!

Oh man! I really want to play this! Any way you can make it available on a Mac OS?

Very cool game, Visuals are really good. I don't know if it's completly random, but sometimes it seems like i'm only getting parts without fishermen.

Nice game, art is really cool, i think adding some kind of background music or ambient sound would make the game better. But overall pretty interesting game and mix of genres.

I've done it untill day 128

At this point it became really hard cause no space 

hahahahah

This is a nice game :D On thing that could be change is to make the tiles appear in another menu. Because at the end of the game you have them spawning on each other, I had a -12 fisherman lol 

Well done man !!!

Incredibly cute! Reminds me a bit of Tiny Islands! Very nice look and it sounds great, a relaxing play for in between :) Thank you for making this!

I literally couldn't stop playing this game. When I saw that one Person made it to day 111 and another to 120 I HAD to beat that highscore... and well, I played to day 137 :D awesome game!

Really cool game! I loved this one, I can see it being something I spend hours on my phone on public transport or something :D 
The puzzle is easy to learn and hard to master, very engaging! 
The art is charming and the sound pops really well :D good job!

Perfect 10/10! Sound design is so satisfaying, The art is just crazy, I love the art style! The gameplay is working very well! Great job!
