Pretty cool game concept. Cute theme. It would have been nice to include the zoom function in the tutorial, as I was halfway through the game before I realized it was possible to zoom.
Now I'm at 74/75 and only the broom is the wrong size. I had it scaled right before, but I had to shrink it to be able to scale the door properly. However, with the door at the right size, I can't enlarge the broom to the right size. This is a frustrating end to an otherwise casual and cute game.
Edit: I was able to hook the broom under the door and complete the puzzle by re-shrinking the window, fully shrinking the door, and then fully enlarging the broom. Just seems out-of-place in complexity compared to the rest of the game.
