I've made a huge mistake. I wanted to update my game on Chrome Web Store, and all I see now is nothing but black when opening the new version.
I don't see any issues when I run the game from C2, so it's a complete mystery to me. The first time I tried it opened up in fullscreen, so I disabled a Requst fullscreen action, but that didn't help.
I also believe I have exported correctly, and zipped all the file as explained in a tutorial about publishing to Chrome Web Store. No error messages is received when I upload the game either. I also tried to delete my cache to see if that helped, but that didn't help either.
I know it's a long shot, but I would really appreciate if anyone could help me with this.
This is the file if that helps.
