Merchant Roads | Caravan Trading & Management Html5 Game
$19Play Demo Here - https://melodic-lamington-d32ae5.netlify.app/### 🐪 Overvie **Merchant Roads** is a complete HTML5 caravan trading and management game built with Phaser 3. Take on the role of a merchant navigating medieval trade routes — buy goods at low prices, sell them for profit across distant towns, manage your crew's morale, hire guards for protection, invest in properties, and build your trading empire. Buyers get the FULL source code — no frameworks, no dependencies, no monthly fees. Just open `index.html` or deploy to any web server. ### 🎮 Gameplay Features - **Live Economy System** — Supply and demand shift dynamically across 8+ towns. Prices vary by region. Buy grain cheap in farming towns, sell it for a premium in mountain settlements. - **6 Time Phases Per Day** — Dawn, Morning, Noon, Afternoon, Evening, Night. Each phase brings new trade opportunities. - **Travel & Exploration** — Click connected towns to travel. Travel costs food and time. Watch your caravan move along bezier-curved roads in real-time with a 4-frame walk animation. - **Visible Bandit System** — Bandits patrol the roads in real-time. Collision triggers a bandit encounter scene — fight, flee, or pay. - **NPC Caravans** — Other merchants travel the roads with unique names and routes. Click them for info. - **Caravan Passive Income** — Deploy caravans that earn gold automatically while you play. - **Property Investment** — Buy workshops in towns for daily rental income. Property values increase by +50💰 per day. Sell anytime. - **Banking System** — Deposit gold for safety, take loans for capital.

Faction wars block roads and shift prices. - **Player Leveling** — Gain XP from trade profits. Level up to unlock more caravan slots. - **Food & Morale** — Your crew eats daily. Running out of food drops morale. If morale hits 0%, your journey ends. - **10-Step Interactive Tutorial** — Overlaid step-by-step guide with highlight regions.
