Just completed the game, it was fun most of the time until the 2 final stages. (heaven sword/Nayla)
Nayla is tanky as F and since it doesn't have Check points between phases its troublesome to start everything from 0 in the final fight, that combined with the low Immunity Frames of the MC. (it would be good if you could add a health bar in these kind of games)
It was fun, and the H animations made it worth.
