Great Graphics!
Great Game Play!
Just didn't feel like a puzzle. More of a trial and error thing.
I think your work has Great Potential because it's easy to see that you spend a lot of time to detail and game play.

Music/Mood/and Graphics are perfect.
As a Puzzle, however, I give it a low 3.

In a Puzzle, ALL of the instructions and information are given up front and the goal is obvious.
There should be no trial and error or secrets, etc.
The puzzle is presented and then a person has to solve it.

Here is the perfect example:
A milkman has two empty jugs: a three gallon jug and a five gallon jug. How can he measure exactly one gallon without wasting any milk?
See! The PUZZLE is given up front. There is no trial and error.

Your software seems, to me, to be more of an Arcade Game. In that genre it would probably rate a high 4.

Nice game!
