This game is hell lol. But in a good way. It took a lot of getting used to but eventually the changes in line density became clear to me. I wonder if there's a way to make it a little more friendly though? For instance if the walls were colored or shaded it would be more clear when you are looking through an opening. Maybe that adds an unwanted reference point though. I just think there's gotta be a way to make it pop out a little more when you are looking at walls at a distance. In my mind the line should theoretically stay solid black regardless of look direction if the game were completely accurate. So I think since you are already playing this concept a little more refinement would go a long way. Thank God for human POV otherwise I'd be totally lost without a tutorial lol. This was fun, great work!
