The polish and playstyle makes this look like a real game. The concept of taking a picture with your phone in order to reveal the ghost plays well into your experiment with putting a phone in the game. The amount of things you can do with the phone (such as playing music, going on discord, looking at previously saved photos) is impressive. The lighting and the mood also plays well into the gameplay. For improvement, I would suggest having a separate UI for the gun, since it doesn't make sense for the phone to be able to count the gun's ammo (breaking immersion). Also having periods where the background music doesn't play (and all you hear is your own footsteps) will also add tension to the game. The 3rd map is also broken and its addition subtracts from the overall game's completeness, making it harder for testers to play the game since they have to exit to replay it. Overall very well done, doesn't look like the work of an amateur.
