Nice Mini SHMUP. I liked the writing a lot. The one thing is I'd like if bombs reset back to 3 with each life, like in standard Touhou. I think that'd balance the difficulty a bit.
Noted ^^ I was a bit scared that would shift the balance too far to being too easy (Mostly due to the boss damage), but since multiple people have commented on that, I'll keep that in mind if I ever revisit this ^^
