The recent Global Game Jam for 2017 turned up 385 games that are under the "Spaced" diversifier. What that means is a whole ton of people have been making and thinking about one-switch accessible games.
The games had to follow the theme of "Waves". I haven't had a chance to pore through many of them, but there's bound to be one or two gems in there. I'll hope to find some time to share some of the better ones.
