If you can, I would take an overview shot of the map to show its layout. I will download this so I can talk more about the gameplay of it.
No there are not. I did my best to make sure that there weren't any spots where the layers would glitch and spaz.
Make a version of the map with no ceiling and another with a ceiling so that way you can get a overview screenshot. It seems not that bad I will download it as soon as I get back online.
