I don't know how to pay with a payment method other than PayPal, but I want to experience new content, can you tell me what other payment methods are?
Hello! I don't know what options there are for chinese users. We use 3 sites where we upload newer builds: SubscribeStar, Fanbox and Patreon and they all offer various other options. You will have to see if they offer something you can use. You can find links to all of them in the game's description.
