In the highway level, it is not possible to almost fall and switch side, as when Joe (the shinobi) go on the road side lower than the ground it is blocked below the floor and fall without any chance to came back. If it switch inside the ground, it is ejected in the up left direction, which make the level slower.
I decide to keep beginning with 0 shuriken as it allows to perform the continuous hitting movement with his sword at the beginning and in casual playing having no shuriken makes the game way harder. Compared to the previous run, 100 less shurikens are taken so the routing changes a bit to save some.
The same goes with the difficulty setting, in fact, it doesn't seems to change anything exept giving you less life, and it doesn't matter in a damageless run.
Furthermore, I like the idea of beginning and ending with 0 shuriken, as it is now.
If there is no comment on it, I will probably submit it like this :
