While I was playing on the math level (I haven't got to the others yet - I explored language a tiny bit) I heard a sirenish war alarm noise. It stopped when I paused the game so it was definitely the game. What does this mean?

Well, I died and stopped my recording. When I clicked back into the game, I heard it. That happened in language level. Another person heard it, when they were looking through a trashcan, also in language I think and another person heard it, when they were solving a notebook in math level. So I guess the siren happens randomly.
