My thought was that this was a really pretty game with an exceptional soundtrack. My feeling was that the theme was evident from the art and the way the game was put together - those aspects were really good.
A few thoughts / suggestions:
* I had a little trouble understanding what I was supposed to be doing - I liked exploring, but I didn't understand if / how I was progressing toward a goal
* I know the main character is old, but I wish he could move around the screen a little faster
* I had some trouble fitting the player character through the openings in the little mazes
Overall, though, I thought this was a really neat little entry. Thanks for putting it together - it was fun :)
