I think you can use debit card or credit card through Paypal, there is an option inside after you click the Paypal icon. It’s going to ask whether you want to log in with Paypal account or pay with card instead, click pay with card and maybe it will work. Please let me know if you succeed.
I am sorry to hear that, it is unfortunate not to able to use cards due to a restricted region or not being supported yet in my country. Perhaps in another alternative, you also can find my asset pack here at https://www.gamedevmarket.net/asset/complete-gui-essential-pack and try to check if their site transaction supports card payment.
Thank you for purchasing my pack I am glad you enjoyed it.
The button animation comes with three behaviors, pressed, locked, and unlocked. You can check them inside the Aseprite file (need the Aseprite software) on the Tag names to see which one they are and what they do. Or you can check their names inside the Sprites folder too. The lock state has 2 types, locked and released, when you use them inside your engine, do not loop them but instead play it once so it will stay still at the last frame.
And what if I bought your asset on this site (https://www.gamedevmarket.net/asset/complete-gui-essential-pack) because I had the same problem, that I didn't have PayPal, and could only pay through a bank card. If you update the asset in the future and add new content to it, will the updated version be available for download from this site or will I have to buy it again?
Yes, I will update the new version as well on the GameDevMarket same as in Itch.io and I think you won't need to pay again for future updates, you can redownload again on that site to get the latest version. But keep in mind, whenever I update my pack to the newer version on GameDevMarket will put on hold on my request for a review, so therefore the update won't be the same day published as in itch.io (usually takes a day or several days).
Thank you for bringing this up, In my next update I will try to help share this product link (from GDM) to here (Itch.io) for those who don't have Paypal.
