This went alright. Luck plays a huge part on this (which is why I stopped). You need 3/4 to be 5 rockets, and then 2 max damage rockets to give the final one as little HP as possible for the ratatatata.

Definitely possible to get sub 60s, but I'm not gonna be the one to do it. Better movement through the maze should sort you out though.
