It does what it's meant to do, and the option to add custom escape music is a welcome addition. Though I have a complaint...
If you want to implement the lap portal, you gotta add it to the map file itself.
While it's not that big of a deal with maps made with the portal in mind, If you want to implement the portal on maps the player did not make, they HAVE to edit the map file, alongside including the SOC file, meaning that the file they'd end up having is just a repackage of one or more maps for just for this addon to work.
It'd be more convinient if you were able to do it with just the MAINCFG file.
Good addon, but the implementation is kinda wacky, that's all.
