i really like the dark atmosphere of the game, and it really felt frightening. i didn't care for the story however because the text went waaaaaaay to slow and you can't really speed it up or anything so i skipped it. but the game i had to play after that was pretty good. what makes this stand out for all the bad FNAF games is the amount of variety the levels give you. and (especially in the beginning) the way of scaring off the monsters. but what makes this one of my favorite horror games are the (surprisingly) good jumpscares. i myself despise jumpscares, but i feel that the executing in this game makes it tolerable (not to mention SCARY AS HELL).
so this game in conclusion is pretty good. so keep up the work :D.
