I think the difficulty curve is off. I beat Mandarina in one go but Ghost has 3 new gimmicks (so far).
Plus, the main mechanic is hard to begin with. I can't see the shurikens turning black and so have no idea how close they need to be for counterattacks.
The powerup mechanic seems pointless as it can be worn down but hits, so it's just a faster way to win as opposed a chance to turn the tide.?
I find that the difficulty does indeed curve awkwardly, but not because of Ghost.
I thought I was choosing a character at first so I ended up going against Ghost the very first time I played and I beat her just fine.
I was surprised to see that the 2nd Boss was able to reflect Red/Gold Shurikens back at you.
I managed to win against all of them in a single go, but the 2nd Boss can outplay the Red Shurikens where as the 3rd Boss only requires you to alternate between Red and Normal Shurikens so that she takes a hit from the slow traveling one as she is reappearing.
