We could just download it, replace the game file in Itch App or run it inside any HTML5 browser / Emulator to play it (Like Microsoft Edge browser, Google Chrome, Firefox, Etc both in PC and Mobile as all browsers run HTML5. I also tried Other apps like Joyplay and it works well all options keeping saves running directly from the file!). You can try to put it in a Google Drive, edit its access to be only acessable with the link, then share the link for us in the game description to play the versions in .html!
