Saw the game on discount and since I really love it I decided to share a copy with someone.
It is a key from humble bundle, funnily more expensive than buying it on steam, but I didn't want to mess around dealing with friend requests and so on.
It may be region locked but I'm unsure about it. Bought in Europe.
If it does not activate let me know.

I hope you enjoy the game, we can play together sometimes if you wish.
