MDC1599: Ninjutsu mode is just like any other playing mode, but one fruit per level has a skull symbol above it - if you kill that fruit, the level is beaten and you get one
(the other remaining enemies are transformed into crystals). And one or two fruits have a heart symbol above them - if you kill one of those, you lose a life.So in total, ninjutsu mode is more difficult and more fun and brings more points than the standard game
has it own spot to pop-up
