Graphics are good!

I almost missed the pliers under a clue stone until I revisited it.

Most puzzles are easy to solve with sufficient clues. The one activated by a compass was tricky. Initially, I thought I had to press four buttons only. Upon a wrong hit, the buttons reset themselves. I knew I had to try another combination. With trials and errors, I received the last gemstone. c:

This puzzle game is okay, but nothing note worthy about it.

Enjoyed it. Fairly straight forward as escape puzzles go, but some of the puzzles were pleasing and the computer-generated/adapted-photo artwork was well done. The mouse drag item was an annoyance...if ever you have to drag something in a point and click a brief note in the menu screen would be great idea as otherwise it just becomes frustrating. As LDeins said the logic to the pyramid numbers is wrong. Replacing the 1s with 4s wouldn't work either. You would need to redesign all the numbers in the puzzle from the bottom up again.
Example:
32-32
8-4-8
8-1-4-2

I appreciate in that example you would need to enter in an extra digit for the answer but you get the point.

Well, if you make some puzzles you should at least make sure they are correct.
The number-pyramid is wrong. The two inner numbers (the 1) need to be 4. only by this the series of numbers leads to the solution by a logic way.

But ok, the game works and has no bugs. a solid 3/5.
