Unfortunately, the game actually closing on you is more hardware related so it is hard to pinpoint. You don't happen to get the black screen at a specific point in the game, right? If it can be reproduced, then my programmer can work on it. If it's random, then that's much harder to tackle!
For now, you can try turning off the graphics enhancements in the Misc settings, this might improve how Tailor Tales runs.
Tailor Tales also requires enough RAM to run (it's very image heavy), so if you find yourself binging on the game for several hours, make sure to save the game, exit, and then open it up again to free up your RAM.
Let me know if the black screen is something you can reproduce reliably, and/or if turning off graphic enhancements works or not!
