Not trying to be over-critical but it wasn't great
I usually try to be nice when I comment on games but... This wasn't the best. It was okay, but the puzzle structure was rather dull. Some color wouldn't have killed it either.
The music however. Blech. I don't see why you picked it. I see how you thought it would fit the, I guess "look" you were going for with the game, but it was just to slow for a game.
Basically what I'm saying you need to work on is pacing. This is something most people have trouble with at first. You can't make it go too slow, this is an online flash game after all, but if you make it too quick your game lacks depth.
