The title of this game is very appropriate, as wherever you look there are walls you can break through, or invisible blocks you can make appear.
In order to complete this game as fast as possible, every little secret must be known ahead of time, and the author clearly exhibits such knowledge.
This movie was made with the Japanese version, 迷宮組曲 (Meikyuu Kumikyoku, meaning "labyrinth composition"), but it is essentially identical to the English version, except for the shop/intro text language.
It is about two minutes faster than the previous version, mostly due to much faster boss fights and more precise maneuvers.
This movie has a full Atlas Map encode, which shows the standard encode overlaid on a zoomed out map.
