You don't live in Russia and don't know anything at all. We are completely blocked. Unless you have a friend abroad or a bank account abroad, there is nothing you can do. VPN does not solve the problem. If it were that easy, it wouldn't even be discussed. Even disposable cards with denominations of 5, 10 or more dollars do not solve the problem. PayPal is closed to us in any form. If you can offer terms for opening an account and paying, please offer, rather than showing your stupidity about what you don't know.
We banal game in Steam can not buy directly, only through intermediaries who created the opportunity. What is there to talk about...
To the developer of the game a low bow, great job. I'd be happy to buy if I had the chance. Only thanks to the group in VK found out about the game in general. So make your own conclusions.
