Nice game! The combat feels satisfying and I like most of the animations. The music is good.
Nitpicks:
- The gameplay mechanics are introduced too fast, I didn't have time to get used to them before moving on to learning a new one.
- The font needs a lot of work. The "n" looks like an "h". You need to adjust the kerning.
- The UI takes too much space. Especially when points pop up.
- The sprites need some work. Which sprites have outlines and which ones don't seems arbitrary. The color usage looks all over the place. A more limited color palette could help.
- The menu transitions are at a different pixel scale than the rest of the game, it looks off.
- I had issues with the audio muting itself.
I would have liked to play more levels. Is there only one besides the boss rush? Anyway, I hope you keep working on your project. I had fun.
