theme: flipped the table, you are the one fighting the hero, not bad.

Polish: it missed some polish tbh, I wish there was soundeffects when popping the circle, but the particles were good.

art: simple art, not bad.

Concept: It's a simple concept, yet it's kinda fun.

enjoyment: I thought it was boring until I tried a harder difficulty, it was challinging it fun.

Seemed like an okay idea for the theme, but not sure if I'm playing the game correctly. I activate the circles and the bar goes up 0.01 each time? And the goal is to fill the bar? I can't view the gameplay video so not sure how it's supposed to be.

It looks like you intended it to be some type of rhythm game perhaps? If thats the case then I see a fun potential mechanic there, where doing well on the rhythm game translates to certain buffs for the dragon.
