telling me it's unoriginal or the artstyle "has been done before" is dumb, like how many games can you list off that have the same style/plot? Probably a great deal of them.
The story/plot is overused in the horror genre. While you did combine multiple stories, they are still just overused. But please remember that this is just feedback and doesn't mean you need to listen to it. That is the point of feedback, it's for people who've interacted with what you have created to say what they think, not what you think.
