It is not necessary to hide a key underground.

That "No clue" text kind of misled me, I thought it meant that it's locked until I find the clue. Besides, why do I have to click three times (zoom in, pick up, zoom out) to get an object? Nothing too new or interesting here; but it's OK for just another escape game. Stable engine, challenge level is fine, graphics also acceptable.
Well... Not bad. I guess. nothing new though and no interesting setting
As per usual awesome game.
