I'm going to post some information on a little something called, "Luna Game."
BEWARE...
Plagiarism go
On April 3, 2011, A game was posted on Equestria Daily labeled Luna Game. It seemed harmless enough, so a few people downloaded it, only to quickly realize it was not what it seemed.
LUNA GAME
The game starts out as you playing Luna on a simplistic platform level, you are able to jump and move around using the arrow keys. But after about thirty or so seconds of playing, the screen cuts out into one of two creepy images; Pinkie Pie Zalgofied or just plain creepy Applebloom. At this point, a creepy song begins to play, and you realize the game doesn't close with the esc key (And the alt+f4 did not work for many people either). The mouse was stuck at the bottom right of the screen too, and the game would always stay on top of every other window. The only way to close the game at this point, was to open Task Manager via Ctrl+alt+del, navigate to the program using the arrow keys, and press delete. The game would automatically close after a while on it's own.
When the user looks at the location he saved the game after it's closed, they find a bunch of pictures and text files labeled 'The End is Neigh', the text file's text also reads 'The End is Neigh'
So yeah, the game is a really creepy game. Especially it's sequels.
tl;dr:Luna game is a game where after 30 seconds (in the first one) Either a picture of Zalgo Pinkie Pie or creepy Applebloom will show up with creepy music, and you can't close the game for about a minute, and when it does close on it's own, and you look at where you saved it, stuffloads of pictures of Zalgo Pinkie Pie (or Creepy Applebloom) will show up, along with dozens of text files named "THE END IS NEIGH," With their text inside being, "The end is neigh"
