It's cold. Too cold.
You wake up in an abandoned log cabin - strange, since you were just in the library studying. 'Must've nodded off,' you think to yourself as you head towards the door... only to find it frozen shut. Outside a blizzard rages, hence the chill inside the cabin, and the wind howls loud enough to rattle the windows. A shiver runs up your spine; judging by how cold it is, you figure you only have 30 minutes to get out of the cabin before you freeze.
Hopefully that's enough time...
