Wow! Play with magic words? Wonderful! I would wanna give it a 4 due to the fact that I'm not a fan of maze game. But this one is fun, the creativity and the magical feelings of the bottom layer make the whole level very special. Most importantly the tools are smooth and easy to use.
What the maze lacked in game play was more than made up by an excellent example of the use of ghost blocks and art. I don't know how you could have made it better! I want to echo @meko 's comment: "The fence floor is a touch of class." Thank you!
@D.S.Masters - The base is so tall because the ghost blocks brought up by the levers are on a fulcrum. For them to reach across to the opposite side of the maze area, they have to rest vertically the equal length below the water. Also, I think it is great and actually imperative (and notwithstanding physically impossible to do so otherwise) that only one lever can be used at a time. Without having to remember which lever raised what part of the maze path it would not be a challenge at all.
