This is such a pretty game, (a little strong on the pan)

but I have no idea how this game is played. Does it have something to do with the number of diamonds on the sides? 

I couldn't find instructions anywhere. Could you add a section about that on the game page's text?

The art is so good, but I was wondering if the pan during the mouse displacement is a feature or just a side effect ?

I enjoyed the over art style/ look-and-feel. 

The zoom was a bit harsh to my eyes. It's a very dramatic movement.

Very cool concept and implementation!
