Don't worry about the missing map change-I've started building the next map, but it's not finished. None of the content in the sound folder is mine, I'll credit the authors when I finish all the maps.
The code prompt is pretty neat too. Maybe this would fit better as an example map?
Map re-uploaded.
Map started over.
