Great!
When I played the last versions, I knew it was missing something, but the addition of the 'Challenge' menu is precisely what it lacked!
Once again, I say it has limitless potential!
(Also, I'm glad no one is so hooked up on the artwork, now that they've gotten used to it. Reading reviews, I'm supprised so few of them realised it must have been for copywright reasons, or else you wouldn't have done it with suck negative reviews about it.
Besides, I like the current artwork; it's by the fans of Lovecrafts' work and so it's a labour of love and that makes it all the more charming)
