I had some problems with resolution on macbook so I had to zoom in quite a bit before I could read the text. That said, this is a pretty complicated game. I didn't manage to find the suspect. maybe an intro level with only 3/4 doors and fewer options would be nice, so the player understands what they ware working towards. Then if they feel the spark, they could continue with a more complicated level.
Very nice job though! Looks like a lot of a effort was put in this one!
