A nice 10!
First of all, I would like to point out that I usually don't vote games 10/10 and 5/5 unless they are absolutely perfect, but that's just it.. Your game is.
It has everything I love in a game: Puzzles, Creative thinking, I needed to use my imagination, graphics, music, a nice learning curve. I mean.. Wow! I was so sad when this game had ended, I believe that I could spend the rest of the day playing this game if I could. I love that there's alot of different solutions to every problem. And I love that you have a sense of humor. (I'm thinking of the section where you pick up the cog, and then are told to think before you act. :P Which I solved by tossing a single 1x1 cube down the hole. :3)
This game made me play all your other games, and favourite you as one of the best game-designers on NG. :)
I want more!
