Amazing map. I loved it.
 Usually I don't go back to a map after finishing it but here I reloaded from last save and explored for one more hour.
 Played on normal skill which was really relaxing.
 Two demos. First ends after I reach the exit. The second one is longer I think and is the exploration and secret hunting.

 I still don't have a feeling for the layout. Just running around trying to find new things.
 I liked the particle effects and the mysterious atmosphere. All monsters are great too.
 Will play again today evening.
 Didn't have any problems with installation/launching the new engine etc.
