Thanks for the feedback, Peter! I agree, since I re-balanced the human enemy aggro range (in their favour) I'm pretty sure that last room has swung from 'too easy' to 'forget that!'. Especially as gold doesn't have much use at the present time...
Re: the music, I had slots for every level and intended the first level to be a relaxing entrance (with according music) - with the music ramping up as everything got darker and more theatening - alas time ran out :) That last level really wanted another music track as it's definitely not such a relaxing jaunt.
