Same error message as princessiiria below re: paying with card.I read your FAQ and understand that there's nothing to be done on the dev side of things but still, figured I would leave a comment for the sake of reporting the issue. I tried paying via PayPal as well, but I hadn't used my account in literal years and ran into what seems to be a common login bug-so no way for me to buy using this method either. D: Would you ever consider offering alternate payment options (ie Patreon store and etc.)? Or is that too much of a risk, financially or otherwise? I'll do more research and attempts on my end - hopefully something will stick. Hope this doesn't affect your sales too badly, as well.
This stings all the more that I was really happy to buy extra 14dwy content and support your work in some way... I don't know if you even remember considering how long it's been and how far you've come since (and honestly no shame if you don't) but waaaaay back then when you'd posted the first build and newly opened the game's tumblr there was an anon who left an overly long gushy post on Ren being such a unique and fascinating character whose characterization was unlike anything they'd seen in the genre or outside, and thanked you for him being so well-written. If that rings a bell: it was me, and I still stand by every word. <3 If it doesn't, know that this game is still my absolute favourite in its category, and although there are very few LIs in this genre I find myself being genuinely into, Ren has had my entire heart to this day (which may be a mistake, but oh well...). Thank you for every update you've published since, every extension and bugfix, and please keep doing what you're doing (as long as you also take care :))!
Edit to add: Managed to purchase via PayPal after a long circuitous process so it's all good here, sending strength to everyone else that's been facing issues!
... I'm hoping the sitation doesn't affect you or fellow devs too harshly- rest assured that your work still means a lot to us players even if circumstances make it more difficult for you to share it.
