Hi, I bought this game a while back through this site I believe, and I remember hearing something about getting a Steam key once it gets released to Steam. I am wondering, how do I obtain my Steam key for this game?
You should have received an email to the email account you originally used to purchase tha game. Thats how I received it!
If you purchased the standard edition from our website then you can email orders@fastspring.com with your name and the email you used to make the purchase and the email connected to your paypal account if that is how you paid.
If you purchased the WIndows Store edition then you claim your key from ingame.
