Sorry, they are independent stores. You should decide if you want to buy it here or on Steam. For my part I could give you a key, but then I would have to do it for all the people who have already bought it here.
ok thank you, i will buy it here :)
It’s done !
enjoy it!
thank you, i will buy it also on steam, to support you !
thank you! Now I'm working on another project and you'll hear about it soon :)
