I didn't enjoy the narration. It was weird how the character introduced that they were using collectibles of themselves as ammunition. It sounded like some type of innuendo. But that's me personally. There's probably someone who would really enjoy that.
I did enjoy the controls and killing zombies. It felt really simple though and I wasn't sure when I won the game or if it was never-ending. A timer or a score counter or something to help mark progression would be helpful.
I did think it was original to have a witch defending her tower against zombies. I wouldn't normally think of zombies and witches together. The art style was cute too. :)
