What a cool game, and a great name to go along with it. I also love the quirky and mysterious music, which at first glance doesn't seem to match a fishing game, but nevertheless very fun and cool to listen to! As mentioned in the comment 2 below this one, the game, with the bubbly UI and touchscreen-like mechanics, felt a lot more like a mobile game, which I think is a category this would succeed well in!
The gameplay was also quite fun, and it was addicting to pick through the trash to find the right materials to fill up a recipe and here that satisfying "cha-ching!" sound. The upgrade system was also quite nice and added more dimension to the game.
Now, as with all idle/clicker/fishing games, there isn't much of an objective other than getting as far as you can before getting bored. It might be interesting to add more mechanics that force the player to make more strategic decisions, and the backpack system is a good start, but it could be utilized better. At the moment, the game just feels like "Pick up all the trash as fast as you can and get as much as possible.", which is what clicker-type games do feel like, but it feels like the gameplay is lacking a more complex level of strategy.
Despite this, I had a lot of fun playing! Consider exploring the mobile game category more, as you are clearly quite a talented game developer. Great job!
