Actually, there is another option called QuestJS (or Quest 6). Version 1.4.0 was released a couple of weeks ago, so it's still in active development. This allows you to write your game in a text editor and run it in a web browser. You can host this on itch.io.
I don't know much about QuestJS, but it has very good documentation on the GitHub web site. You can migrate a game from Quest 5 to QuestJS, but it may require a bit of editing to get it to work. Perhaps check it out and see what you think. The author is active on intfiction.org and the QuestKit forum (QuestKit was an earlier version of QuestJS), so you may be able to get help there if you need it.
