You are a private investigator. 
Look through the phone given to you, to find the solution to your client's question.

Connect the clues using the connections of the person whose phone is in your hand.

Controls:

Everything: Mouse

Toggle cursor visibility: C

Based on early feedback, controlling the phone is a weak point of the game, so I'd recommend toggling the cursor visibility, whenever you struggle with it. 

In the future I'll improve this aspect.
