Yes this uses portal bumping to show newcomers that they shouldn't do this in their maps.

Yes this isn't a very good map I know, it is to show newcomers that they need to use lighting, prevent portal bumping and not use portal surfaces under things like fizzlers, This was to give advice to newcomers who have done this, I know it isn't a good map, because on all my maps now I don't use portal bumping in any way, I use lighting and the rooms are alright, anyway this was more to give advice to newcomers so they can see this isn't good.

This is What New People to the game should know about, read description.
