Source code released
After some cleanups and improvements, I’ve put online a new downloadable ProtoRPG bundle that includes proper source code. A few comments :
- The game can run locally, but you still need to download Prototype and Script.aculo.us separately and save them in the /javascripts/ directory.
- I’ve included a functional, if somewhat crude, map editor.
- There’s also a sample PHP script to handle server-side savegames.
As usual : software is provided “as is” with no warranty, use at your own risks 
This is one fantastic piece of work. I am already messing around with it and it’s very fun!
One thing I can’t seem to figure out is the code for monsters. You know the habitat and density. Those rats are powerful too! Anyways, great job!
ONE YEAR SOURCE CODE ANNIVERSARY.
