Hello! When you hit the download now button here on itch.io, it will give you the option to input an amount of money (in this case it just has to be 4.99 usd to access the DLC edition)! I think it may convert the value through your payment system (I’m not 100% sure though 🙏)? Otherwise, we expect to have the Steam release up sometime this month before October if that’s more convenient!
