That was a great experience :)
I loved it!
I don't have any problems with the game,
But the steam key, I didn't find it.
I checked at My Purchases and I have also clicked the Download button below the game, but no Steam Key.
I also checked the mail I've got when I bought the game, but no key.
AND when I downloaded the game, I also checked the folder if the key is in it, but no.
To be honest, It's OK, because I had a great time with Enypnion, so XD
Again, Love It!
