Honestly, I think it ultimately comes down to what you want done with your work. Personally, I think the Silent Tower *IS* what it is, because of the puzzle-explorer type of super-area that it is. It's an area that I've only made it into about six times, died horribly without a sound each time, and absolutely hate because I can't figure anything out (I've never been good at puzzle areas). However, I see the changes you propose as a watering down of the area into a lesser form. Being the vindictive sort that I am, I would personally see it as a sort of "I gave you this shiny toy, and people abused it, so now you lose the toy". Unfortunately, the only people that it really punishes are those who aren't trying to abuse the area, and the work you've put into it. Mostly since those who you're trying to stop, aren't going to care either way, and internet semi-anonymity really prevents much further than that.

On the other side, as I mentioned, losing the area really is more of a punishment to those who don't deserve it, and your work as the writer. I don't see it as the area the writer invisioned, but it's still more of what you wanted than it sitting in limbo. On the plus to that, maybe I can actually survive in there ten minutes!

Functionally, I'd rather have an area to play in, than not, but if you'd rather the area enjoy it's full justice, I think it's perfectly reasonable if you don't want it to exist in any "half-ass" state.
