If a company is interested in buying the source of your game, I would say that is your .capx file in Construct 2. The output javascript is automatically generated and not easy or useful for anyone to look at or modify. The true source is your Construct 2 project. Giving someone the .js file is like giving someone asking for the source of an EXE a huge assembly listing instead of the actual C++ code, which you'd only do if you wanted to annoy them!
Thanks for explaining!
Well maybe we do what they want, i guess we should to offer them as consulting.
