The art style is great! Love the music and sound effects too. And the projectiles that your gun fires are just amazing, especially with the counter in the bottom right.
Only thing that kind of bothered me was your own projectiles hurting you. I feel like that wasn't conveyed very clearly to the player and caused my first death to be very confusing. Also sometimes you can poop out a bomb and a bullet which then bounces back instantly to hurt you, without you being able to do anything about it. At the same time, dodging your own stuff does add another layer to the game, so that's good!
Maybe an idea would be to not have bullets hurt you in the first second or so that they spawn, so it's always in your control and your fault if you get hit. Still an awesome game though, I had a lot of fun, good job!
