Neat game. I liked how some of the upgrades changed the way your bullets work rather than just simply making them better. Music felt a bit mismatched for the gameplay though imo.
You said you didn't have enough time to add more than 3 abilities that you get from dying. While that is fair, I think a small amount of extra exp could've worked as a filler option. Would take the sting out of losing a life a little bit once you've obtained all 3 of the abilities.
I tried to do a run without dying, but I unfortunately encountered a bug. At one point when I leveled up, the game broke (see image below). I was at around level 11-13 when this happened.
