Steamworld Dig, from back in Humble Indie Bundle 12

This is a fresh key that was listed as unredeemed until I revealed it for this giveaway. So far, I've had one fresh Humble Bundle gift link fail to work for a giveaway winner (out of 50+, along with hundreds of personally-used HB keys), and tech support won't help because I'm not giving it away to a personal friend. Please only enter if you'll agree to delete this giveaway if this happens to be a second bad key.

I try to schedule all of my giveaways for when I'll be available to deliver them right away (no one likes to get notified about winning, only to check back for days to see if they actually got their prize or not!). Please don't forget to mark it as received once you get it!
