What is the best strategy for the funky arcade?

you can sparkle hunt the zombies on the elevator level. Also, the section where you're supposed to jump off their heads, if you fail that QTE, you enter into hand to chainsaw combat with them, also enabling sparkle-hunting, which provides an endless number of 4-group zombies to rack up points on. What took my victory over Dad was that I died twice during the arcade sections, which count as continues, which docked me 10k points.

Bullcrap.
