Hi Phil, thanks a lot for your interest in the game. I've checked and your payment is on hold for now. Just to avoid any misunderstandings, the game is in no way finished. It is an ongoing work and new chapters will be released as soon as they are completed. Right now the game is undergoing a little rework. I'd recommend to wait a few days, approximately to sunday, and the reworked version up to Chapter 3 will be released.
If you still want to, I can tell paypal to release the payment and your 20$ will be paid. But if you want to wait till chapter 3 is out, you can also still reclaim your payment. I'll leave it up to you :)
Best Regards
