At night it's colder than outside

You have to go home. It's late, the streets are getting dark, and now your phone is running low. There are strange silhouettes on the side walk, and they don't look friendly...

Can you make it home safely?

For the ones wondering if the title was written by a third grader: the game's title originates from a german nonsense-sentence: "Nachts ist es kälter als draußen".
