Like Deaaz, I also didn't quite realize what the coundown was at first, thinking the effects would appear at random (which they still feel like to be honest and effectively are to the user as they cannot really control them). I would find it more interesting if you had more control over the gameplay and there was some more strategy involved.
I do really like the evidence board and the art in general in this game, it does look really good!
Also I accidentially clicked "unload" from the unity menu in the bottom right once so the game just stopped lol
