Keys SettingIndeed, Ninja Tooken is a complete game! But no worries, you can modify absolutely all game controls whenever you want.
So, go to the menu "Options", then "Controls". You should see the complete list of the actions with the associated key. And if you have any doubt about an action, you just have to put your mouse on the corresponding text to have an explanation.
Then nothing is more simple, click the button corresponding to the key you want to modify and press on the one you’d rather use. But be careful, do not assign the same key to several different actions, because the previous action will not work any more...
These modifications are on your computer only, so if you play somewhere else, do not forget to do it a second time!
By the way, you will notice that from the same menu you can modify the mouse sensibility: the more it's raised, the more your ninja will turn quickly.
