I absolutely love your interpretation, and the concept of tampering with stuff to change who is the main suspect along with the different suspect options was really cool. A few suggestions would be 1) add audio, 2) make more of the items actually change when you interact with them. I found it confusing that the blood pools didn't actually disappear when I cleaned them, and 3) consider making the rooms a bit smaller or zooming out the camera a little as I sometimes found myself not knowing where to go or what to do because of how massive and empty the room I was in seemed to be.
