404: The End of All Things
Well, it looks like you're lost. The universe has ended. The last star has burned out. The last thought has been thought. It's all over. Don't bother trying to find your way back, the fabric of space-time has collapsed in on itself.
However, if you're feeling particularly adventurous, you can try exploring the vast expanse of nothingness that lies before you. Who knows, you might stumble upon a forgotten sock or a lost earring.
Or, if you're feeling particularly masochistic, you can try Loop the Loop for a chance to relive the same 404 experience over and over again.
