Question: HOW THE HELL DOES DOUBLE DEFENSE TAKE 6 HOURS?! You don't even need adult, all you need is bombs to megaflip to it. That doesn't use ISG or keys. Someone plz explain.
1. You're thinking of double magic.
2. Bombs/chus are banned.
3. There actually was a faster way to do this with a seam walk, but it wasn't part of the puzzle. If it's banned, this puzzle would take 3 hours minimum.
