Break strangleholds
If you get too close to a regular Shibito, it will sometimes prefer to grab you by the neck and choke you to death instead of doing a regular attack. When one takes you into a stranglehold, rapidly move the Left Analog-stick Up and Down.


This will break the hold, and prevent you from dying.



Time attack mode
Complete the 1st 2 objectives on all levels in every scenario to unlock the 1st ending sequence. Now, press Square at the scenario selection screen.
