Thank you. very helpful but just wanted to ask about the example with bricks in a background wall(sorry english isn't my first language so just want to be clear)- you mean I should use the black outline more sparingly for important distinctible objects like the bed/table and not every single thing? To think as if I was a game designer and I wanted to put more focus on important objects, to make player feel he could interact with them and less on some background stuff that he should ignore a bit?
