Nice ability and original level. Thanks! Spoiler: Question @richardfu is it possible to solve it going inside the vehicle? I wasn't able although I really liked such idea...
@richardfu Spoiler I tried that but B always fall out of the platform. I just let the vehicle remove as much zaps as it can and then come walking with B at the right moment when remaining zaps are at the borders.
I solved it in @chemi's way! I thought that was intended. Will try again, really cool twist for a sequel! Thanks.
