Vampire Survivor clones are a dime a dozen, and this doesn't really innovate.
Do you know WHY Vampire Survivor autofires your weapons and goes for minimal graphics? Its to offset the mental load of a complicated screen to just "move your character". It largely doesn't bother with a story because that's not what you're there for.
I respect you're trying to innovate but really, think about it. F button for laser, shift for books, hundred of enemies on the screen? If you make it full manual, are you marketing to people who enjoy Vampire Survivors, or Starcraft 2 vets?
What's here is functional. Can't really give it much more than that.
