The level unfolded by itself once one part was moved so that there was very little gameplay but it looked good.
I love the design, especially the roof. Not sure how I got B out from the start but I did. Very clever mechanics. Then I got right to the win block but couldn't reach it. Of course the answer was obvious! I got 4 out of the 5 stars, which is also my rating.
@ohmytian yes, I didn't understand why it sometimes goes slower but moving the release mechanism speeds up
