KaiOS is "a web-based mobile operating system that is based on Linux kernel forked from B2G (Boot to Gecko), an open source community-driven successor of Firefox OS which was discontinued by Mozilla in 2016. (As written on its Wikipedia Article)
I wanted to use Unity Game Engine to make a game for it but I have not seen KaiOS as one of the available platforms to build for.
Is it possible that one of the platforms that Unity builds for (such as HTML5) can be made somehow compatible for KaiOS? Are there any other available tools I can use? Or will I have to work on the raw game from scratch?
