Alright the game is awesome with a few nitpicks.
I like the designs, the music and generally how it looks.
I dislike the sheer amount of flashes that you get from turning on the flashlight anywhere, the engine you chose works (Unity) but maybe try getting into learning how clickteam works? Clickteam can make your life MANY times easier and I'd think that it would be better for the game and how it would run. Also adding subtitles to the phone calls would be nice.
As a sidenote I know that as of now there are only the main animatronics, but working on distraction/smaller threats could work in your favour as:
People would have a better time with 6 different animatronics at lower speeds than 4 animatronics at fast speed.
Besides these few things your game could work out well, but I suggest to get a group of people to betatest every update and give feedback so that your releases are received without many complaints.
