Select one of eight different characters to begin. Each character
has a unique set of moves, represented as a deck of cards. On every
card you'll find a name, damage amount, energy cost, and a 3x3
grid. Use a movement card to move in the direction of the arrow on
the bottom of the card. Using an attack card will subtract the
card's energy cost from your energy bar and, if the move connects
with your opponent, the card's damage amount is subtracted from
their HP. The red squares on the grid of attacking cards determine
the area affected by the attack. Each player also has a guard card,
which will protect you from up to 15 damage received on the turn it
is played, and an energy up card, which will restore your energy
bar by 15.
Both you and your opponent choose 3 cards to begin each round,
which are revealed one by one as the action unfolds. As a reward
for defeating a foe you get a shard of the Shikon Jewel and the
opportunity to choose one of five mystery cards to add to your
deck, granting you abilities such as special attacks, enhanced
movement or healing.
