Guest received a mysterious invitation. Oh? Looking at the sender... it seems to be from quite far away... no, from deep space outside of Earth. There are red stains on the edges of the invitation, and the 'kind' message 'If you don't come, I'll come find you!' glows unpleasantly. But what is this Morse code written at the bottom? It's piquing your curiosity.
