I should have known better. Fiction told us not to mess with time travel. Authors told us not to write about time travel. Physicist told us time travel is really bloody difficult. And I thought: Yeah, for you it's difficult. But I've got it figured out.

On the upside: I did get it figured out. On the downside: it took me two days longer than expected.* So day seven will be a mad dash to implement everything else. Surely, I can handle that. 

*I could've dropped the time travel element instead, but hey, I'd already made the header image.
