This movie is merely 1 frame faster than the previous one by HappyLee, due to faster wall-entering on "Stage -3", which was considered unimprovable.
I was just curious about how useful the new acceleration method could be, which this movie shows, and made it in less than one hour. "Stage -1" is made a little more humourous, I think.
I would like to see new tricks found to improve this movie further.
