MetroMap.io is a captivating simulation game that allows players to design and manage a minimalist metro system. The game challenges you to balance construction costs, train operations, and rider demand to complete as many journeys as possible on procedurally generated maps. Inspired by the Mini Metro style, players place stations at grid intersections and connect them using metro lines restricted to clean 0°/45°/90° angles, reminiscent of Harry Beck's design. Passengers spawn based on surrounding population, time-of-day, and land/water constraints, riding your network using pathfinding and generating ticket revenue upon journey completion.

Key Features:

• Procedural maps via seeded RNG ensure consistent world generation.
• Stations snap to grid intersections; lines are immutable straight segments.
• Passengers appear in catchment areas, preferring destinations by time-of-day.
• One train per line to start, with acceleration and deceleration mechanics.
• Score increases with completed journeys; finances track build and running costs.

Players must strategically plan their metro lines, considering map types such as rivers and archipelagos, which introduce additional challenges and costs. The game also simulates population density and demand, with varying passenger spawn rates and preferences throughout the day. MetroMap.io offers a unique blend of strategy and simulation, providing endless replayability for enthusiasts of urban planning and transportation management.
