Thanks for playing. I can see the difficulty is a problem via reading comments. But i also see that once a player knows the strategy, the game will suddenly becomes very simple. Hmm maybe i should improve the learning curve.
As you have mentioned there is some element you don't quite get it, i would like to mention some fun fact. The weird dialogue sfx is from Cantonese Opera's percussion. It's played often after an actor finished a monologue. And for the "card" projectile that protagnist is throwing, it's not really a card. Song is actually shooting a fulu spell, like Reimu Hakurei is shooting Ofuda. In real life, both are just soft paper printed/writen a spell on it. You are supposed to keep it as amulet or stick it on object, not throwing it as weapon. The hp symbol is fulu amulet fold into a triangle.
I recently got a character idea for Player 2 character. I feel there may be a cultural shock when westerners see it. The Player 2 character will be a paper dummy servant who throw hell cash.
