Generally a nice-looking and well-executed game.
I did feel that the text speed of dialogue was excessively slow, and would have liked space to advance to the end of pages of dialog instead of skipping unfinished paragraphs entirely. Simple changes to this UI would have made the plot more enjoyable.
In gameplay, I rarely felt that there was any reason not to hold down fire continuously. A charged shot, a limit on projectiles in the air, an ammo limit, or any number of other mechanics could make firing something that benefitted from careful timing.
