Hello.
I sent you the game as a gift, if you can't receive it due to regional restrictions, I will send you an item from the inventory so that you can sell it on the market and buy the game, and I will throw you some keys as a bonus

If the key did not work or you had any regional restrictions, you should write a comment on the giveaway page so that the giveaway creator can try to resolve the problem. I see that the game is now in your Steam library, and you have marked it as "Received", so everything is fine now. Thank you.
