Instructions
Jump frequently. This prevents your enemies from getting a clear shot at you. The power of all enemies' attacks is higher in Insane Mode, so it is best to not get hit by any of their attacks.
Use the left analog stick to move around a lot during battle. This prevents you from being a sitting duck. Some enemies can kill you with one hit, so moving around makes you a harder target to hit.
Press the "Square" button four times in a row to do a series of quick attacks. These attacks allow you to get in some quick damage before your opponent can hit you.
Press the "Triangle" button three times in a row to perform a heavy attack combo. This makes it easier to get in a lot of damage quickly.
