Go Line 🧵

Connect the City.

Go Line is a zen transit management simulator. Draw colorful transit lines to transport passengers, managing efficiency and flow as your city grows.

Stats

Core Identity

Go Line is a strategic transit puzzle with a clean, industrial aesthetic. Every line you draw stitches the map together. Every delivery keeps your network stable.

Key Features

Progressive Network Expansion

Start with a single red line. Complete shifts to unlock new colors—Blue, Green, Orange, Purple—and build complex multi-line systems.

Day Cycle Management

Manage your network through timed shifts. The Day Progress Bar tracks your progress. Each successful day earns currency and unlocks.

Systematic Upgrades

Spend Thread (currency) in the shop to improve your fleet:

• 🚆 Add Carriages: Increase train capacity for high-traffic stations.
• ⚡ Faster Needle: Boost train speed to reduce wait times.
• 💪 Network Strength: Handle higher tension and overcrowding.

Interactive Camera & UI

• Industrial UI: Metallic textures, progress bars, clean typography.
• Pinch-to-Zoom: Explore your network with intuitive gestures.

Smooth Geometry

Draw curved, stitched paths between stations with touch-drag controls. Quadratic Bezier curves and dashed patterns create a clean, handcrafted look.

How to Play

1. Connect: Drag between stations to create a transit line.
2. Deliver: Transport passengers (geometric shapes) to matching stations.
3. Manage Tension: Prevent overcrowding. High tension leads to network failure.
4. Advance: Complete shifts to earn Thread, buy upgrades, unlock colors.
