I cant find it anywhere, what is the garage skip?

Quick questions.

1. In the arcade version, is there a way to change difficulty? I don't seem to see why categories are in Very Hard. Sorry I'm new here.

2. In the arcade version, when submitting a run, is it required to just use 1 playthrough with 3/4 health or can we keep on dying and use a lot of "continues" for infinite lives as long as we get the ending?
