I'm sorry man
You establish a wonderfully suspenseful atmosphere and sharp animation.
But, unlike your other games, the interface is very annoying.
For instance, it's nice when items grow in size when you try to click them in your inventory, but why would you make them displace up? Every time I wanted to click something I found my self having to constantly reposition my mouse. Why?
The boxes that open to reveal items, would it have really been that different to make it so that by clicking anywhere on the box would have opened them instead of the very tip top? I spent an hour in this game only to realize that I could open two more boxes by clicking the sand on top. Really?
And puzzles based on random motions without any sort of clue? I turned the jade wheel at the end over and over for fifteen minutes and it never clicked. And before you say it, I went slow, really slow, and just for kicks and out of utter frustration I went really fast. Nothing. REALLY?
Sub-machine games usually leave me with a sense of awe and wonder for the next game, but this one pretty much ruined my day.
Hard puzzles are fun, but KEEP THE MECHANICS SIMPLE!
