"Around the corner" is playing with a bit of a cheeky mechanic that was nearly cut (and maybe should have been). Thank you for the comment :D
Had to use a small hint, and I'm a little mixed. On the one hand, the mechanic used is very interesting, and not touched upon in SSR. But on the other hand, the block not falling is softly breaking what felt like a very fundamental rule. Maybe the puzzle, using one-turn movements, could have used an enemy as a timer with you setting the blocks up beforehand?
