You did great with the theme, you interpretation of dirty and clean was very well used, and some puzzles actually made me think. The only critique I can give is that somethimes the physics are a little bit clunky, and the aiming reticle isn't always representative of where the mouse actualy is.
I reached level 8, unfortunately it was too hard to come back to the beginning to exit it, but overall the game is pretty cool, congrats!
