So I think I may be out of luck here given how it's been six years, but figured I'd try.
I backed the kickstarter for this game way back in 2012 but never actually claimed the reward (a time of great turmoil in my life). I had completely forgotten about it until I got a email promoting a sale for the sequel.
I did a search through my Gmail and found what I think was the link I was supposed to use, but it seems to take me to a backer page for the second game now. Is there any way to still claim the game?
