Super cool!  I noticed that this game was inspired by Enter the Gungeon which I loved playing and this game did remind me of it.  For the gameplay, I think the enemy projectiles would benefit from being slightly slower but have more of them fire at once.  This may give the player a bit more time to react while still engaged in dodging so it feels less cheesy when you get hit.  I also loved the cutscene art and the epilogue at the end!  Nice work!
