Cool game. Only major thing that bugs me are the unresponsive air attacks.
Something you are too far away so the attack won't reach, other times you get hit by the enemy bumping into you although you definitely pressed the attack button beforehand.
Especially annoying in the boss fight where you don't get a hit but rather lose 2 lives thanks to enemy bumping into you and then have to wait another eternity for that asshole to finally get back within reach! >:-(
