I completed it yesterday morning, and I really enjoyed the "color key" puzzle. I went on ZQuest, and do my eyes decieve me, or did I just see
Spoiler: show
Sillycat2: I think it works on any build later then 864, any earlier build (or 864 itself) will crash ZC.
EDIT: Got bugs?
First, the Switch Hook option of the Hookshot often flies off in a random direction if used. No, I mean the chain literally flies off and breaks when switching with a monster occasionally. Not only that, but you're left frozen in place with an invisible Hookshot, after which you *groan* have to restart or *bigger groan* cheat.
Second, by holding up at the web after using the hookshot, you can get out of it. May or may not be a bug.
I'll find more as I go on.
