Thanks for the extensive puzzle feedback, guys.
WRT Tikki 3, by the way: that's actually been adjusted so that your solution is the intended one. Or at least, I've trimmed off most of the extra stuff that isn't related to it. Still trying to think if there's a more elegant way to deal with that, but eh ... it seems REASONABLY smart, anyway.
Also, doh ... the animated armour in Taurog 3 was supposed to be a little more complex to engage, but I suppose a slightly simpler solution overall can't hurt.
Gnome 3 *was* slightly altered, but I've been rather conservative with changes on that one ... I think this particular puzzle is rather famously delicate (it has been broken more than any of the others) and in clamping down I've probably made it difficult to see what's going on. I'll try give it another revision this week, just need to put a little more thought into player expectations and how to deal with those.
... aaaand just checked, I definitely didn't make it impossible this last week. But I've already got one or two more ideas to help limit the possibility space.
