Apparently The Smuggler is unavailable for download by using the official Itch app. Just putting this out that you can find out how to make your game compatible with it by using the official Itch developer section just for it.
Thanks for the heads up. Can you please try again? There was a UnityCrashHandler exe in the root folder, I think that was confusing itch because there were 2 exe files. Please let me know, thanks!
