just some random guy walkthrough, there are many ways to play the maze like: 1. you can go for the easy route/faster route rush to the near end stage to get good high rank buff, however there is only 5 stages if im not mistaken. 2. gather good low rank buff with (max: 3stars stacking) for better damage on boss (Shark) which I highly recommend for non-veteran.
