I don't think it's hard, I think it's unplayable.
Bullets are too fast to avoid them (no other bullet game matches this speed). When you get hit, the character rotates and shoots in a different direction from where you're aiming, making it impossible.
It's not clear how much damage a bullet does, I got 3 lives, but I can get a lot more shots.
Also, what is the character? Why am I fighting flowers? These questions would make you fit the theme more.
