    "Native builds need a C compiler, make and SDL2 development files, plus the user's Keen 1 data files including KEEN1.EXE; the README lists v1.1 and shareware v1.31.",
    "Browser builds require Emscripten and supplied game data; the documented web packaging is restricted to the shareware episode. Browser shortcuts and per-origin IndexedDB storage differ from the native host.",
