To obtain the (not yet released) binary file:
1.) view the frame source of the js emulator on the game's itch.io page
2.) follow the "js/content.js?v=0.404" link
3.) copy the "var g_prg" string content & save it in a text file
4.) go to a base64 decoder site, that allows file upload
5.) download the result and rename the file to something.prg

edit: A proper download is now available. :)
