It isn't by choice that I want such reverse engineering. The client received the exported files, unminified, and the game is in a "more or less 80% done" state. According to the client, the original developer all but vanished on him and didn't deliver in time, and hopes are low that he will, especially since this is a classic conflict situation where both parties feel in the right for whatever reason, but my client is additionally under pressure from HIS client that has set a tight very last deadline to deliver. Whatever the reason for it, I'll just have to work with what I got, thank you for your help!

Hello there, I'm completely new to Construct2, but experienced in javascript and html5 development and game development in general - just in Unity as of late. Anyways, a client approached me with a "halfdone" project in order for me to finish it, but he only seems to have the "build output", meaning the game itself is operational and the source code is there, but I do not and seemingly cannot get my hands on the construct2 project that created this game. Is there any way to "reconstruct" the project with this output? I of course do not expect to magically get my hands on PSD files that created the graphics, but it would be very nice not to have to work on a 768 kb single source file named "c2runtime.js" where I have to sort through the parts that belong to the engine and those that belong to the actual game by hand.

I am well aware that the most probable response is "you can't", but I thought that it can't hurt to ask. Thank you for your help!
