Do you live in a country like Germany or China that's banned AO Games on the store? If so there's not really anything you can reasonably do to get the game on Steam, you'd have to use a VPN with a different region store and giftcard a lot can go wrong with and probably isn't worth it.
I'd recommend getting this version if you can stomach using a different store, this version is Early Access anyway while for as far as I can tell Steam only has the Demo currently.
Unfortunately Germany. And i found out about the ban a few days after i wrote this comment. Well i guess i have to buy it here. I would have loved to buy it on steam but i guess there is no othe option. It's not a problem to use this store, payment method is my problem. Thank's for the reply, i really love your game.
