Hi yotsimitsu! :) Paypal should allow payments by card, but you can send me a donation through a link on my itch.io page and I'll send you vaunchers to claim those assets. You can check what is the conversion rate from USD to EUR before you make a donation :) I'm working on updates for PSX Mega Pack and PSX Tunnels Kit that to be released today, so I'll get back to you pretty quickly! :)
