Quick little giveaway (2+) (Over)

Here's a giveaway for Rebel Galaxy. I got it from the Humble Monthly but didn't want it so I figured I'd give it away.

16 piece puzzle to weed out the bots.
Edit: Since I always get questions asking what to do with the code at the end:
In your URL box, type "www.steamgifts.com/giveaway/*****/". Replace the stars with the code you received after finishing the puzzle.
Edit 2: There's no SGtools check on the giveaway since I'm lazy but I will check for unactivated wins and multiple wins.
