As an uploader of the video,I can't help but write something.
I uploaded that short video about a month ago,and few people could recognize the seriousness at that time.Maybe it's because I was speaking Japanese in the video,but it disappointed me for a whole month
Now,I'm very happy to see many people,even the developer,understand the situation.
Special thanks to bing12345 and tightrope.You are my heroes
