I think that there could maybe be a texture around the edge of the walls? I noticed that sometimes there was, but iIcould only see it with the small vision circle around the player...
Thank you! About the wall textures, there was, but with the way the tilemap and player vision cone was set up, it was creating shadows over the buildings where the player's vision collided with a wall. It was one of those things that I was unable to find a solution for in time.
