# About Island Economy Simulator

Island Economy Simulator invites you to a tranquil yet challenging island where your survival depends on your fishing prowess and economic decisions. You start as a lone fisherman with a simple boat and a basic fishing rod. Each day presents an opportunity to catch fish, which are crucial not only for your sustenance but also for improving your fishing operation and the island's small economy.

The game features a charming visual representation of your island, complete with a dynamic day/night cycle, an animated fisherman, and various fish swimming in the water. As you progress, you'll invest in upgrades like a fishing net to boost your daily catch, and visit the local market to purchase enhancements for your boat or equipment. Your goal is to build a sustainable fishing enterprise and survive for as many days as possible, carefully balancing your resources to avoid starvation and economic collapse.

## How to Play

Your primary goal in Island Economy Simulator is to survive by managing your fish supply.

-   **Start:** You begin with 3 fish and a base productivity of 2 fish per day.
-   **End Day:** Click the "End Day (Fish &amp; Eat)" button to progress. This action will:
    1.  Make your fisherman cast the rod, and you'll catch fish based on your current productivity.
    2.  Automatically deduct 1 fish for your daily sustenance. If you don't have enough, it's game over.
    3.  Advance the game to the next day, triggering a visual day/night cycle.
    4.  There's a chance to catch bonus fish each day.
-   **Build Net:** Invest 1 fish at a time by clicking the "Build Net (Invest 1 Fish)" button. The net requires a total of 10 fish invested. Once complete, it significantly boosts your productivity by an additional 3 fish per day.
-   **Visit Market:** Click the "Visit Market" button to access a shop where you can spend your surplus fish on various upgrades:
    -   **Paint Boat Red:** A cosmetic upgrade costing 15 fish.
    -   **Improved Rod:** A planned future upgrade (marked "Soon") that would increase productivity, costing 30 fish.
-   **Monitor Stats:** Keep an eye on your "Day," "Fish" on hand, "Productivity" (fish caught per day), and "Net Progress" displayed at the top of the UI.
-   **Objective:** Survive for as many days as possible. The game ends if you cannot provide 1 fish to eat at the end of a day.
-   **Progression:** Accumulate fish, build the net, purchase market upgrades, and strive for a high score represented by the number of days survived.

## Features

-   **Engaging Resource Management:** Carefully balance catching, eating, and investing fish to ensure your survival and economic growth.
-   **Progressive Upgrade System:** Build a fishing net piece by piece by investing fish. Visit the market to purchase items like cosmetic boat paint, with more upgrades planned.
-   **Charming Visuals &amp; Animations:** Enjoy a visually appealing island setting with a dynamic day/night cycle (sun/moon), animated fisherman casting his rod, a rocking boat, visible fish swimming in the water, water ripples, and visual feedback for net building and investments.
-   **Day-to-Day Survival Challenge:** Each day tests your planning. Aim to survive for as long as you can.
-   **Random Events:** Experience occasional luck with a 15% chance each day to catch 3 bonus fish, adding an element of surprise.
-   **Immersive Sound Effects:** Sounds for actions like investing fish, net completion, catching fish, bonus catches, purchases, and ending the day enhance the gameplay experience.
-   **Automatic Progress Saving:** The game automatically saves your progress in your browser, so you can pick up where you left off.
-   **Mobile-Friendly Design:** Play seamlessly on your desktop or mobile device browser.

## Controls

The game is controlled entirely with mouse clicks or screen taps on mobile devices:
-   **Main Action Buttons:** Click on "Build Net (Invest 1 Fish)," "End Day (Fish &amp; Eat)," or "Visit Market" buttons to perform actions.
-   **Market Interaction:** Inside the market, click on purchase buttons for items (e.g., "15 Fish" for boat paint) and the "Close Market" button to exit the market panel.

## Tips & Strategies

-   **Prioritize the Net:** Your first major goal should be to complete the fishing net. Investing 10 fish to get a +3 productivity boost is essential for long-term survival and accumulating surplus fish faster.
-   **Safe Surplus Management:** Always ensure you have at least 1 fish remaining *after* any investments or purchases, to survive the "Eat" phase at the end of the day. It's better to wait a day than to risk starvation.
-   **Plan for Market Purchases:** Once the net is built and your daily fish income is stable, start saving for market items. The boat paint is cosmetic, but keep an eye out for functional upgrades like the "Improved Rod" if it becomes available.
