Cleared on version 1.0 almost all the bosses were too easy including feathered Hong and Zhao. Beat all of them under 3-4 tries.
The tiger however was brutal with his rapid attack through no i-frame down animation. Beat him after 25 tries.

This game is really weird for me because most games are frontloaded but this game level design and music gradually becomes better as you progress throught out the story.
I wish enemy type had more variation tho.
