Ashley, it may be too late now, but would it be a far fetched idea to make a Construct 4 with the engine in C++ or Rust or any language that can be compiled to WebAssembly, and make the web runtime with WebAssembly ? That would be the optimum way, of course harder then the current one. WebAssembly is shaping up pretty nice, i'm impressed. Or, another nice option would be to have native/web hybrid progressive web apps with WebAssembly running as exes in the machine, with lightweight exe sizes. Well , one can dream :)
