I likes it.
You've improved your flashmaking skills enough to make it much faster and more fluid during the opponents card sequences. Thats noticable.
Extra additions to cards are also nice touches.
Though the one thing that bothers me, and no offence to the artist is the new artwork for the cards. The old art from the first game captured the cthulhu feel just perfect. Dark, wierd and incomprehensilbe when showing the beasts, but vivid enough to show whats there.
This new art appears too comic-bookish and cartooney.
The music is one of the saving graces to capture the mood and something I think should be kept in any future updates.
Keep up the good work though.
Fhtagn! Fhtagn!
