Hello, you can change the sensitivity in the option (press [esc]) The first puzzle is to figure out the potential with the clone and the lockpick but we didn't have time to make a proper tutorial. I take note for future jam to enforce the tutorial because you are not the first one who struggle with the first puzzle (The solution is to take the lockpick, open the door, find the stone, use it to return in your cell, your ghost will open the door and then now you still have your lockpick to open the second door)
