The premise of Mini Metro seems simple enough: design and build a subway system that will shuttle the citizens of your imaginary utopia from point A to point B in as safe and efficient a manner as possible. But then your population starts to skyrocket, and you don’t have enough train cars to keep up, and your stations keep filling up with angry people who really, really need to get home, or to work, or to the hospital. Sound familiar?

The full, downloadable version hasn’t been released yet, but you can play an in-browser alpha — which is plenty engaging on its own — here.
