This is a great game!
It's pretty challenging, I even died and restarted few times until I get used to the bosses attacks, especially when their HP getting lower they become more fierce!
Idk if it's just me but when I died the boss hp and the player are not refreshing and carried over, no not the actual HP but only the graphic, the actual HP remain as is, obviously it's updated right away when taking damage.
Oh, right... I don't know if I'm cheating or not but I abuse Air Dodge on 2nd boss like a lot (I also did on 3rd but not as often as I did on 2nd), there's no mention about whether player can Dodge while in the Air at the tutorial so I'm not really sure if it's a legal move.
There's nothing I can add I guess? anyway Nice Work!
That's all I guess, if I write something wrong or missed something, let me know.
