I really liked the dramatic lighting. Maybe adding the option to show everything you can interact with, like in point and click adventures, would make it a little less trial and error...
Originally we wanted to have a full examine, use and combine point and click system, so lights would be increased globally to decrease their challenge. However, we had: TIME CONSTRAINS.
It's a pity, but lights had to be left like that to create a challenge without the other systems.
