I liked that you didn't use straight forward generic puzzles. The clock puzzle was by far my favorite, and the sand pit puzzle was good because it wasn't straight forward. Changing the sand puzzle made for a greater difficulty.
The story behind the game was great. I liked that it was told partially by finding the newspaper clipping. Excellent plot.
The music was very appropriate. The audio overall was great and added to the atmosphere. The graphics were great and I loved that the camera wasn't always stationary (I.E. the subtle shift when you first leave the room.)
This game was very well done. Adding to favorites, and you have 5 stars.
