I must confess, my original post on optimization of game levels was, well, incomplete and inaccurate. Optimizations were not fully complete. There were a lot of T-Junctions that were left behind after optimization (, Sandeep was probably the only person to catch that). However, I managed to remove those too. They were causing a lot of problems with A* navigation and I am glad they are gone! So here are the updated screens. Some extra level geometry has been added so the screens might not look exactly the same as the earlier post.
