Duo Park Walk

No video to compare gameplay but i am not sure if i have the designed gameplay. I was surprised that the the ball beside zapper , which was nearest to starting position of B, would fall differently when pushed face on by R, depending upon which direction R got to grass block two blocks away in front of the ball. This and the tendency for B to hover over the metal steps made it difficult to get a consistent gameplay. I used deliberate stack instability in my no trick win.

@ridgerunner - Whoops on the video - just slipped my mind. Thanks for playing, commenting and rating.

Spoiler: Video Solution

@Meko Guy ..the only significant difference in our gameplays is at 4:50 . I ran the stack past the overhead wedges which always dislodged L.

This video shows the failure of the ball to roll with a different approach. I thought the nice low ceiling move allowing B to return was typical of one of your gameplays.

@ridgerunner - Good find - of course, that low ceiling was introduced late in the build as I wondered if players could sneak under so I added another block and never thought to check for low ceiling.

Two significant differences in this very nice clean logic level...

Spoiler

1- I did what @ridgerunner said in his first comment after his valoration &
2- as I did not see the stack you do to carry L to the zone to push the highest ball, I pushed the second ball that fits the hole with the two balls with B. As you said "cancel tap may be requiered" & casually in that zone has an effect on B,I had to use it to perform that step.No feelings of cheating

thanks @Meko Guy well done!
