re:fracted

Congrats, wagie. You've got a few dozen letters, limited fuel, and a lot of deliveries to make. Get to it.

Your route is yours to determine-  so long as everyone gets their mail.

Deep space gets lonely, so why not take a peek at the strange and varied letters the denizens of a universe without communication send?

Along your route you may notice some anomalies. Don't worry! You're not in danger...

...as long as nothing sees you inside.

Do not worry about the lack of exits.

Do not worry about the knocking.

And remember to stay in the dark.
