I'm really sorry to hear this comment but this is last update on ruffle engine, i'm making my engine alone in unity over 9months for now and trying my best to make it workable on all android 7 and above with 32 and 64 bits.
I'm single developer making engine called UniFlash for Mac, Linux, Windows, Android and maybe Web version and iOS version too
Please be patient for new engine and video will be unploaded when i make first workable fps
