To develop for this game you need to be aware of the code structure

All location/event code is compiled into a single file Javascripts/compiledplaces.js

The source for this is in Javascripts/Places(Source) and there is a bat file that creates the combined file using the Google Closure Compiler or simple copy commands. I leave it as an exercise for those using a unix based OS to convert to a bash script. Not this process just combines the files and does a simple whitespace strip.

So the process is edit the js file, and then run the compile script, and test.
