Possibility to pause the world and continue moving is great skill. Pause ahead offers it but you still need great timing to make your ninja survive.
Don’t be worried by dying, it will happen many times. Your possibilities are very limited, because the ninja hero can only jump. Oh, and you can stop the time while your hero continues to move. This give you huge power to overcome all the deadly obstacles. The idea is very original giving you some addiction to the game. But the difficulty keeps high and you are going to fill several morgues.
