Fight of the Tatsujin

I made this game for the Gamedev.js game jam in 2 weeks with the theme 'Power'. This is a rhythm game looks like a fighting game in Japanese art style,and the moves have rock-paper-scissors style relationship. Increase your power, complete the dojo challenge, and defeat the master. I'm terrible at English, so the English texts in the game are bad either, I hope they're readable.
