Stack cards to captain a desperate train in this frozen, apocalyptic, and totally free roguelite demo

A cute little proof-of-concept game has picked up attention on Steam in the past few weeks: Frostrain, a card-matching game about conducting a train of apocalyptic survivors through a frozen world ala Snowpiercer. Getting stronger requires you to build up a hand of the same cards, all of which represent train cars to expand your new demesne with.

At the same time you have to set a course through the wasteland outside, navigating by terrain and such between nodes that represent snowfields, polluted wastes, cities, and famous landmarks.
