Slightly disliked it in the beginning because the desert areas were a bit too monotonous and open, resulting in some confusion. But I stuck with it, and I'm glad I did.
I found all items and the genie, and was quite OP on the lower floor. The Nyarlathotep fight, while not exactly easy,wasn't difficult either.
Adding some landmarks to the desert areas would be nice, and I suggest making Nyarlathotep, and the enemies on his floor, just a bit tougher. But then again, I don't know how balanced that would be without the genie and the secret weapon.
Will we be able to import the saves into the next chapter? If not, I don't see the use of all the crafting components. Or I missed something.
