So, I'll review this fun card-drinking game in a bit, but in the meantime:
You'll want to fix the Kuji-kiri/Kuji-In, or else not only will you have seasoned Ninja warriors after you, you'll also have Taoist/Buddhist Monks and Wizards after you as well!
The Kuji-kiri goes:
RIN
PYO
TO (like "Toe")
SHA
KAI
JIN
RETSU
ZAI
ZEN
(the bold ones were incorrect in the game). Like, "Pyo" is normally called "Hei" (soldier, like HeiHo, "Art of War"), but in Mikkyo or esoteric buddhism aka Ninja Magic, it's read "Pyo". Same with the others.
Please see to it that in a revision this is fixed... Before more innocent blood is spilled.
