Several are missing. Are those the free ones? It'd still be nice to seem them added, because it's better to be able to download to PC instead of play in a web browser.
It's a real shame that the dev didn't include a girl protagonist option like in the rest of the Betsy series. I guess he decided against it, despite some initial signs that he'd be working on both guy/girl protagonist scenes. Oh well.
The reason the free games should always be downloadable or in a torrent is after you play a game one or several times, redoing the story can start to get boring, but if you downloaded the game, you can find & rerun some of the scenes.
