Frostline: Ski Escape

You draw a line down the mountain. There is a bear behind you, and it does not stop.

Frostline is an endless downhill ski run played with one thumb. Weave through the trees, jump the rocks, slide under the low barriers. The slope keeps getting faster and the obstacles keep closing in - the further you go, the less room you have to be wrong.

THE BEAR IS A CONSEQUENCE Every mistake brings it closer. The fourth one lets it catch you. Ski clean and it falls back: the bear is not a timer, it is a mirror of how you are playing.

CONTROLS Swipe left and right to change lane. Swipe up to jump, down to slide. That is all of it - five seconds to learn, hard to put down.

STREAK AND MULTIPLIER Every obstacle you pass cleanly builds the streak, and the multiplier compounds your score. One collision resets it. The whole game lives in the tension between going fast and going carefully.

CRYSTALS AND POWER-UPS Collect crystals on the way down and grab power-ups: a shield, a score multiplier, and an axe that lets you cut straight through the trees for a while.

A MOUNTAIN THAT CHANGES Dawn, blizzard, night, glacier - the slope keeps changing shape beneath you. Every run is built from a different set of patterns, so there is nothing to memorise.

DAILY RUN One slope a day, the same for everybody. Same patterns, same luck, different hands.

AN HONEST GAME No ads. No in-app purchases. No internet required - it works on a plane, underground, or up a mountain. No data is collected and nothing is sent to a server; your scores stay on your phone.

A single run takes two minutes. The problem is that a single run is never enough.
