Eis~, your mapping is simply amazing. Pretty messy, but all the compartments are working out well with each other.
There is just one logical mistake in your 'way to demons' work. The thin wooden bridge to the right just isn't correct - I know that the pillars are burning, but in that temperature it would dissapear within 5~ minutes. Changing it into stone or metal could do better.
Other than that: Epic win, as Cykotitan has said.
