Well done. It's is a very balanced game with nice graphics and high replay value. I do have to agree that it's a bit overly reliant on luck rather than strategy, but maybe that's more of a matter of taste. I would leave the ladder even if though it's not functional at the moment. It adds to the sense of mystery.
Cheerio!
