My OSX version work on my Mac just fine but as soon as I zip it and upload it to Dropbox or itch.io (a game sales site) then redownload it and unpack it, it won't launch. I experienced this same problem with another Construct 2 game The Way of Yiji, when I bought it from itch.io.
I get this error when launching from the command line:
LSOpenURLsWithRole() failed with error -10810[/code:185vgb76]
I don't have this problem with Linux or Windows. Anyone else have this issue or have a solution?
UPDATE: I discovered the culprit, Keka. It's a file archiver for Mac. Apparently it mangles .app files made with node-webkit. Why or how? Not a clue. I used a different archive tool and things work fine.
