Nice Work!
Tbh I'm having a little technical issues running it in browser but that's probably only me as I used to seeing these when I running godot games on browser, I used Firefox btw.
Luckily it has downloadable version so I'm good.
I don't really know what to add as the bosses are pretty challenging but doable, probably? as I'm having a skill issue with the second boss whose very ruthless but that's just probably me.
The game fits the theme and everything else are fine as well.
That's all I guess, if I write something wrong or missed something, let me know.
