It works well and I still use it with friends and family to play games together. I even designed a logo, registered it for an EU trademark, and made t-shirts.
But when Steam Remote Play Together was announced, I decided that there wasn't a market for it anymore, so instead I switched to building real-time AI tools in C++.
My next idea, funny Webcam filters for desktop, was then pre-empted by Snap Camera coming to desktop. With so many FAANG-scale companies releasing free tools, it has become really tricky to find financially viable niches.
