How Many Lines Do You Need?

Today, I took on the "City of Lines" achievement in Mini Metro. The challenge was simple: survive on the Paris map using only **three lines**. It sounds easy at first, but with such a small network, every line has to do a lot of work. I didn't get an amazing score, but considering I only used three lines, I'm really happy with how the run turned out. More importantly, I finally unlocked the achievement! As always, I would love your feedback on both the gameplay and the video quality. I'm always trying to improve and make better content. ❤️
