Love the menu work! Overall the game was a bit of fun but I agree with others that some extra clues would be useful. One thing I found challenging was when the prop was right on the other side of a wall and so the cough was loud, might've been worth casting out a quick ray to see if any walls were blocking and lowering the volume as if it was coming from another room.
Love the use of the Synty assets though, the area looks great, and the sound design is really fun. Good work!
