We also made a game called One Armed Bandit :D From your description, it sounds a bit similar so we wanted to give it a go.
Sadly, when I try to launch the .exe, i get the following error:
[Window title: ALERT!]
Error: Could not load game data at path '.'. Is the .pck file missing?
I think you need to add the .pck along with your .exe and possibly other files to a ZIP archive and upload it on itch.io :)
I'm running Win7 64-bit SP1.
