I downloaded and installed this through the Itch-app under Manjaro Linux. There is no executable, just mp3 files and png files in the game folder.
Downloading it from a web browser its fine, get the SWF file and can play it with Adobe Flash Player.
I built the Linux version on a version of Ubuntu that fits on a thumb drive. It wouldn't even run properly but others said it was okay. I've no idea how Linux stuff works so perhaps it's similar to a Mac app where it's a folder full of resources.
I can't even get Linux to work on any of my machines any more so I'm afraid I can't offer anything else. The executable did nothing other than run the swf in a wrapper. So if you can play the swf you're playing the game - the exe or app version isn't any better.
