seconded. it really only takes a bit of trial and error to finish it, and after each section of the maze it'll even give you a head start against the dusknoir. maybe try saving during the chase when you can? that might alleviate the annoyance of restarting the maze over and over
and yeah, besides a final chase in chapter 15 that doesn't send you back to the beginning when hit, that's the only chase sequence in the game
