Quite liked it, but subtracting a star as B didn't push one ball and no retry could be done as B moved away from claustrophobia.
I really like this one. It's an interesting route and good looking design. Thank you. BTW I had no problem pushing the balls, but there is a hint to help with that in the list of tricks.
I liked it but didn't do a Stop Claustrophobia to get the ball to fall correctly? It's a good thing too as I probably would have walked away knowing that sometimes your balls don't fall right!!
It is not difficult to find the path to the win but the individual steps do not always have the right effect.
