The visual are nice, the player attack animation looks super smooth. The control feel nice, and the music are cool too. The gameplay are interesting, I like how the two bosses have different approach to the theme which makes the gameplay feel very different.
The bosses are cool, tho the boss on the right feel a bit too easy compare to the right one, as the boss rarely attack you if you just stay inside the fire ring.
But still, really cool game!
