Project Lemons

A cozy lemonade stand economy simulator

Welcome to Project Lemons, a systems-driven management sim where a big city hides a surprisingly competitive lemonade economy.

Start small with a single stand on a street corner. Manage your margins, and try to turn a profit. But, you’re not alone — rival stands pop up nearby, weather shifts demand, neighborhoods develop their own personalities, and every decision ripples through the local economy.

This is a game about reading the map, understanding demand, and out-thinking your competitors.

Controls

• Right click a building to open the interaction menu

  • Use the Yellow lemon icon to Build (if none already exist)

  • Use the Red lemon icon to Sell a stand (if one exists on that building)

• Drag with Left Mouse Button to move the camera around. 

• Scroll to zoom in/out.

• Progress is auto saved at the start of every day. Access your save data from the Settings menu (Data is saved locally in your browser too, so no need to keep tabs on your save code!)

Deep, Data-Driven Economy

• Buy and manage supplies (lemons, ice, cups)

• Set prices dynamically — too high and customers walk, too low and profits vanish

• Wealth, demand, weather, and competition all factor into sales

• Track profits, daily sales, lifetime earnings, and growth over time

This isn’t idle — it’s about optimization, timing, and strategy.

Rival Stands with Personality

• AI competitors open and close stands dynamically

• Each competitor has unique behavior: aggressive pricing, high margins, expansion-focused, or reckless

• Rivals can undercut you, starve demand, or go bankrupt if mismanaged

You’re not just playing the market — you’re playing against it.

Dynamic Events & Weather

• Weather directly affects sales and customer behavior

• Notifications keep you informed about competitor actions, events, and market shifts

• The world reacts to what’s happening — even when you’re not looking

Designed for System-Lovers

Project Lemons is built around emergent gameplay:

• No scripted solutions

• No fixed “best” strategy

• Learn the systems, adapt, and grow

Whether you enjoy spreadsheets, city sims, or watching complex systems unfold, this game rewards curiosity and experimentation.

In Active Development

Project Lemons is evolving with:

• More events and weather types

• Expanded competitor behaviors

• UI polish and visual upgrades

• Long-term progression systems

Feedback is welcome — this project is being shaped iteratively with systems depth as the priority.
