I might be missing something, but isn't the original Impact a JavaScript & browser based engine, thus it should run on Android in a simple Web view just fine?
Most of that repo appears to have been built in early 2013. Android WebView didn't switch to chromium until late 2013. Prior to that it was usually an older hacked up WebKit sometimes provided by the phone manufacturer with unreliable features.
I remember working on a QC app that used NFC and a webview right when I think the first Pixel phone came out, basically to track QC steps while expensive equipment went through a production line. Was a somewhat painful, but interesting experience. I'm not sure if I liked it more or less than dealing with Palm/Handspring development a few years before it.
It's funny, I actually forget some of the small, one-off things I've worked on over the years.
Ejecta was a project that implemented WebGL with JavaScript bindings -- basically everything you need for a web game without the DOM. It implemented enough of WebGL to run Impact-based games.
