Avalanche

It's sunny spring and you've gone on a challenging hike to the High Tatras despite the increased danger of avalanches. Since the days are short, you have to leave the alpine hut in the morning. In the morning, you are woken up by a loud noise and you don't even know it - the cottage is overwhelmed by an avalanche. While searching for an escape, you come across a long-forgotten secret of the cottage. The sun rises inexorably in the sky and the avalanche danger increases. If you do not escape within 70 minutes, the ceiling of the hut will collapse for good and you will perish there.
