Ideas for Free Horror Indie Game

So I have this idea for a indie horror game. I know, a lot of horror games out there already but I want this one to be different from others.

First of all, in the game you play as a paranormal investigator. Maps would be completely Free Roam and the main objective would be to find substantial evidence to prove whether a location is haunted or not.

Ideas for locations;
-Abandoned Prisons
-Old Theaters
-Old Lighthouses
-Concentration Camps
-Restaurants
-Hotels
-ETC (End of Thinking Capacity)

From the main menu (which will preferably be interactive) if you were to press the button to start the game ("Play" or whatever will be decided on), the screen would shift to a van, the camera positioned in a way to look as though you were sitting in a chair. The van will have monitors inside it, and they will be used to select a map to play on.

Once inside the map, you start out near the van (back doors will be open, revealing the equipment and whatnot). From a table outside the van you will get all your necessary equipment (Flashlight, EVP Recorder, EMF Meter, Ghost/Spirit Box, Thermal Camera, Full Spectral Camera, any other possible equipment you would be able to think of).

All these different equipment will serve a crucial part in this game and will be used to capture evidence, which will in the end be used to decide whether a location is haunted or not.

Nowhere throughout this game can you be killed or injured, although there will be minor jumpscares throughout the maps.
