No build step, no npm, no config — single HTML file.

• Select a tower from the build bar, then click any land cell (brown terrain) to place it
• Right-click a placed tower to sell it for 50% of its cost
• Click ▶ SEND WAVE to release the first wave of enemy ships
• After each wave clears, the next wave auto-launches after a 15-second build window
• Lose a life for every ship that reaches the exit — you start with 20
• Earn gold for each kill; spend it on more towers

Sell any tower for 50% of its build cost by right-clicking it.

Wave composition scales with wave number — early waves are patrol-heavy, later waves mix in tankers and destroyers.

Each map uses a real-world satellite basemap (Leaflet + CartoDB Voyager tiles) with an accurate land/water mask. Enemy ships follow a hardcoded BFS path through the navigable water channel.

• 🗺️ Real-world chokepoint maps — same geography as Strait Command
• 🚢 4 enemy types with distinct HP, speed, and reward profiles
• 🏗️ 3 tower types with range preview on placement
• 💰 Gold economy — earn from kills, spend on towers, sell for half
• ⏱️ 15-second build window between waves; click to send early
• 📡 Map-specific geopolitical news ticker
• 🌊 Wave difficulty scales automatically — no wave cap

Strait Command — same maps, different genre. A naval strategy game set in the same chokepoints.

• Adaptive enemy paths — between waves, enemy ships reroute around heavily defended corridors, probing for gaps in your coverage. Towers become high-cost zones in the pathfinder; open water stays cheap. Players watch the path indicator shift and pre-empt it.
• Additional maps (Suez Canal, Bosphorus, Panama Canal)
• Tower upgrade tiers
• Special abilities (airstrike, naval bombardment)

• Single HTML file (~800 lines)
• Leaflet.js 1.9.4 — map rendering
• CartoDB Voyager tiles — light theme satellite basemap
• Vanilla JavaScript — no frameworks, no build step
• Canvas 2D — game rendering overlay

Coloured with scandinavia-01 · SNÖ — first snowfall, frozen lake. Matches its sibling Strait Command (same maps, different genre): frosty body, deep-teal command towers, brick-red hostile fleet.

Palette pulled from Rangrez, the global colour-palette library that backs all NakliTechie projects.
