Thanks for the lovely post a few posts ago, Mitsy. A thoroughly enjoyable read. I know that may harbor a 25% doubt here and there, but I'd personally consider it a landmark of the modern era when it comes to gaming revolutions. I wouldn't even dare to use a word so demeaning as "impressed" because it couldn't even touch the very edges of the raw power that your efforts have so lovingly and diligently produced. Everyone I've ever displayed the quest to in video form was similarly impressed. If only they knew the age of the engine under the hood.
Another thing you might want to add to the list of potential bug-fixes is "Clue in Tower of Seline room where Whirlwind Song is required." Although there is a Music Note on the floor, I'm pretty sure that the first place you actually have to use that song and some people might conclude as MeleeWizard did that it only warps you to the beginning of the dungeon.
I actually second, third, and fourth this. It's one of the areas that people very often find themselves stymied. The Whirlwind / Block All mechanic is extremely rare and unknown, and isn't one of those things that would make a lot of sense initially. I'd even go so far as to say that that bottom-right room in Seline's Tower might need even more of a spoiler. Maybe a drawing on the back wall of the room featuring a whirlwind and a block all block with an arrow pointing from the wind to the block. That would more than do it.
Yeah, most of the puzzles I find myself stymied over all revolve block all blocks, come to think about it.
