The Fall of the Dungeon Guardians GA...key must be redeemed by 9th March. (Level 1+)

So apparently I missed the fact that this particular key has a deadline. Saving grace is that Fanatical sent me a reminder email.
Key must be redeemed via Steam before Friday, March 9th 2018 at 23:59 (PST).
So if you are the lucky winner, please activate quickly :)
