Absolutely amazing entry! So so much fun even tho I have yet to beat the last level, I plan to give it a bit more time (I GOT SO CLOSE). So Polished!

I Seriously had fun, it was hard but fun hard. I do enjoy hard bullet hell type things tho

If I had any feedback there is some small things:

The lives were kind of hard to keep track of, I would suggest stealing the idea from "Just Shapes and Beats" where the played shape is the health bar as well, since you will be you will be looking at the player from time to time anyways. (Its hard to explain what they do I recommend just seeing a video of it. But the gist is the player sprite changes based on lives by cutting the player into sections)

I would be so happy with a quick retry button, in games like this sometimes I would get hit then instantly want to retry, to do so here I have to hit tab - main menu - click level. Not terrible but hitting T or R to retry would be soooo nice. 

Final small thing would be some sort of progress bar on how far you are / got. Maybe cuphead style where it is shown after death? 

Thats... kind of the only things I would like to see. Your game is so great that those are the only changes I can think of, and to be honest considering the jam time, its unrealistic to have added those things.

Seriously if I could rate, I would give all 5s. 

Congrats!
