Incredible that you made this solo! The game is visually stunning with smooth animation. And the music choices are great! I like how after each death there's different music! The combat is smooth, and it functions exactly as how you expected it will. The sprites and the particles are beautiful.
To make this game even better, I think the screen shake can be more subtle. My eyes physically hurt from playing. I die more times due to not being able to focus on the character because of the screen shake than actually misplaying. Also, the hp bars can use another color for improved clarity. The game becomes exceedingly if you just hide in a corner, so you should fix this too!
Overall, the game is incredibly well-made. You should be very proud! Great work!
