Hmm. The black bars appear for the cutscene, the other girl runs across the screen, and it just gets stuck there? If so, I can imagine what's causing that, although I tested just now and couldn't reproduce.
Sorry about that. Where is this black screen? Is it after you select New Game, or just immediately after the Unity splash? The current build works on my computer (Win 7) so I'm not sure what the issue is.
Oh right, you can try deleting your save file if you haven't already. If the game crashes while loading, it just shows a black screen. On Windows it's in AppData\LocalLow\Scarlet String Studios
