Managed to get past the 4b mark. I had the random idea to skip the extra bomb you can get from the area 3 boss just so I can go for higher overkill. I don't know if that'll bite back if I figure out proper routes for the later stages. If I hit up easy again, I'll probably see if I can make some variation of this work while still getting that extra bomb. Still not too sure how to route out each stage since I'm kind of just winging it. Do feel I goofed up a few parts. Trying to utilize all the tools you get with type-s feels a bit beyond my level.
