Fresh out of the banya, a crew of fishermen foolishly drift off on an ice floe after the legendary Tsar Pike. Day after day they float further out — and every evening an old van hauls them and their catch home to the village, where fish become upgrades.

• Drill, fish and keep the floe from tipping over. Everything is hands-on physics.
• Keep each other warm. Save each other. Or don’t.
• At the strait, the van picks you up — the ride home is in the back, not on a loading screen.
• In the village, the catch buys upgrades for your floe and sled, and the map opens the next bay.
• Somewhere out in the farthest bay, the Tsar Pike is waiting.
