I am closing in on finishing the first draft of the payment and distribution system for https://soapspangledgames.com/. I’ve been working on it part time for about a year, and have finished the credit/debit card payment system (using BrainTree/PayPal), and downloads after payment are complete.
The system is in sandbox mode, so cards are not charged, but the entire payment/distribution lifecycle works although I have much more administrative stuff to implement. Although cards are not charged, the system still allows downloads for those who complete the sandboxed process. Essentially, the games are free for now.
