Hi,
Scene 4 begins once you return to MoonHell's bar via the browser.
I don't really understand what you call "executable" on Linux. I am testing the game in Ubuntu and have not encountered any problems. In addition, I have a Mac in addition to my PC. For Mac, just unzip the file, this will create the executable. If that doesn't create an executable, be sure to unzip through Mac's decompressor and not third-party software.
No worries, if you're creating on Windows, it's something that's out of your power to change because Windows' File System works entirely differently and doesn't "know" something like an "Executable Bit" - as Linux and Mac OS do.
So, it's easy to set the executable bit - in many Linux Distributions, you don't need to use the Terminal to set it, but just right-click the file, and then set the permissions in the "Properties" Menu.
