I have never been as confused with a bug before.
If the bg and the character were missing, I'd understand. If there was a error message, same thing.
However bg and NO character has left me completely lost and I see nothing that could cause this.
If you can send me a dm on twitter (@tightly_dev), I can give you a debug version of the game (that shows additional info on the console) so I'm able to help you with this.
