You may have to wait some time for the first scene to load -- I'll add in a loading screen in the next version, but the first scene doesn't have a loading screen which may be why you're seeing a blank screen while everything loads.
How long have you waited for the screen to stop loading?
Yeah, these load times aren't ideal -- it looks like there is some optimization I can do.
It looks like I have some preloading options that were defaulted when I exported the game which may be the culprit -- instead it could load a lot of these files on the fly since they're infrequently referenced.
