Im giving this a 4 because of the ability to deduce stuff is much more complicated, I guess there are more people with patience who are willing to give this a 5. But as a simple minded person to solve crime , it was pretty rough for me to sit and click around for fun. The environment was designed perfectly and overall i liked it. I would have given it a 5 if i could have use my brain to the minimum and solve it.
Good Job!
