Thank you, I'm so glad you like Catset :)
Itch does provide other methods of payment for customers, but right now Paypal is the simplest and best I can do for now, sorry. I will try to look into it and see if it's possible for me to set up more options, when I get the time.
If you want, you can email me at info@seethingswarm.net to get you Catset
