Timing, reading R's movements correctly, and B won't be zapped. @ADM | I'm not sure if the rating you've given is reasonable as you haven't solved this level completely.
My B is terrible at soccer and even worst when under pressure. My B finally dropped the ball but not after way too many tries. When I got to the hidden section I just gave up as I don't do hidden.
Nice combination of ability and logic. Balls were really hard to push with B so I had to force little bit draggables usage. Thanks!
@gmacpro Spoiler use draggables to push the balls (second ball can be bypassed by stone path by the way). And the hidden corridor is an easy code puzzle, search for the visual hints.
