It turned day 29, I let o-kerfur out, and then an event started happening where it started crescendo-ing louder and louder whilst it got brighter and brighter. I hid under the desk and a gigantic flashbang explosion went off, nearly killing me instantly. When I stood up I apparently hit my head on the desk and died.

^ About the only piece of information that looks like what i was talking about.

Sky Fall. This is a reference to the cartoon Chicken Little. There should be a white hexagon nearby (after restarting the game it is black).

thought so, it just didn't seem like it. Probably because of where I was.

This?
