Thank you all for the kind words. I am enjoying playing in it.
I feel slightly embarrassed at the moment though.
I had tested all the links to discovering the two hidden rooms and was confident they worked (and they do), but I neglected to add a necessary keystone. Doh. :oops: I thought I had added it but used the wrong choice when prompted. Doh again. Yikes.
I placed the missing keystone and tried to upload the lot again, but the Exchange won't let me.
All I can do is ask for mercy and advise you to use the buydebug cheat to acquire the correct keystone when you get to that point. SO SORRY!
