Your Thoughts? Horror Game Tools Creation

Hello my name is Brandon and I’m currently working on a horror,

So I’m currently working on in game tools the player can use but before I start I wanted to mention the the general idea is a combination of dead by daylight in phasmophobia,

The first tool I’m thinking of is type of sensor/motion tracker,

The first part of game involves going to a location in a team of 4 to 5 people and find clues about what creature your dealing with it will contain puzzles, locked doors that sort of thing,

Then second phase is being hunted while solving a objective to escape,

That said currently the first tool can act like a EMF detector I added a twist that involves changing frequency often to match creature, this is used for active areas and creature belongings,

The second feature is a heartbeat type of thump that lets you know if a hunt is happening and blips get faster the closer the creature is this feature also stays on at a reduced range when put away unless turned off,

The catch is the device make noise so the player has to be aware of this,

What sort of things do you think in regards to this do you have more practical ideas?

Thank you for your input as my first time horror creation I appreciate any input.
