Strong back half, but doesn't really start with its best foot forward. It does introduces a traversal mechanics pretty late, i.e. the very last level. I get they want you to go back to each level, but "replay everything but this time with a couple extra goodies to pick up" is not compelling game design. Solid platformer, funny enough script, and good use of the IP. Battle for Bikini Bottom is still the stronger entry, though.
