I died 5 times in a row as I just couldn't get the first tap but after I did then it was kind of slow and repetitive. There wasn't a need for the three zappers as only one gets B. So I'm providing feedback - I hope you use it. Zapper dodging isn't my specialty but I won.
Tricky steps but, even if B misses the slider and lands on the rail, it is possible for B to climb back on the slider.
