I have played with Obfuscator a bit longer and I like it even more. The only problem that I've seen (although it didn't really affect my game anyhow) was that when I changed the level script in map properties of WED, it has shown an error message saying - "Line too long!". But it worked fine anyway.

The last and very important thing: I think this tool is great and there will be many people who would use it with pleasure, but the main thing for you as it's author would be to refrain from creating some de-Obfuscating tool. Otherwise all these manipulations wouldn't make much sense...
