Shovels&Shivers

I started digging a snow tunnel system throughout my yard, making spaces for sleeping, places to keep warm, and caches of food. On day 3 I became disoriented and just kept digging. I am somewhere in the city, under the snow, but I know not where.

The battery in my phone is low and it's getting dark. I think there's something in here with me. I hear voices. A shuffling sound. Send help. Hurry.
