Controls are customizable in this game that features attack, defend
and jump moves for the little blue ninjaman in addition to the
standard arrow keys for movement. Default configuration is: [D] for
attack, [S] for defend, and [space] to jump. A double-jump can be
performed by pressing [space] a second time while in the air.
Attacks can be combined with arrow keys for some spectacular
special moves and abilities:
* [up]+[D] = Uppercut: smack enemies into the air
* [down]+[D] (in the air) = Sacrifice: dive down onto enemies
sword-first
* [down]+[D] (on the ground) = Whirlwind: slice and dazzle enemies
with a series of circular slashes
* [up]+[right or left]+[D] = Ballista: hurl enemies with a powerful
smash
* [down]+[right or left]+[D] = Sonic Slash: thrust enemies away
with a devastating force
* [D]+[D]+[D]+[D] = 4-Hit Combo: unleash a flurry of slashes
