Hi, glad you like my games. I didn't know paypal and stripe no longer operate in your country. You could try downloading my apps on google play or app store, and check if they have more payment methods to purchase the pro version and remove the ads.
Yes, hello again, I have already downloaded all your games via Google Play, checked that all your games are really super, but, to be honest, I wanted to notice something in one game called Marble Wars, I would like to see not only multiply by 2 functions in the "multiplication" mode and a shot, but to have such, for example, +5, +10, *3, *5, *10, It would be really great.
Well, I'll try to figure out the donation somehow in order to purchase some of your games not only on the phone, but also on the PC.
