The music is such a banger right out of the gate! The art is really great and the controls feel so nice.
I wish I didn't have to repeat the tutorial every time I died... because I died several times (in the first room, even, but I think that's just a skill issue haha), and it got annoying to have to keep replaying the tutorial. I also wish the reload was immediate, or at least faster. I lost track of how many shots I had while trying to dodge the incoming enemies that I'd get cornered because I needed to reload.
But the music is so good, the art is so nice, and the gameplay is so smooth and satisfying that I still felt motivated to improve and to keep trying despite how frustrated I might have been feeling.
