Wow, quite some professional graphic and smooth game play, even in browser!
I'm somehow stuck after finding a jewel and clicking on it. A box appeared, but I could not find out how to close it again and to progress the game.
I'm also a bit confused about these eye things standing there after an attack. What do they mean? I'm a bit lost. I might have figured that out over time, but due to the above mentioned bug, I stopped for the moment.
