The gameplay loop is simple: you fish, collect fish, and sell them for coins. You can then use those coins to buy better rods, bait, and other goodies. It's a never-ending cycle of fishing, collecting, and upgrading!
The goal is to level up your character and unlock new areas, like the elusive Elixir. You'll need to fish up a bunch of rare fish and treasures to get your hands on it. It's a challenge, but it's so much fun!
