Hi,
I've been interested in accessibility and making games for blind gamers for a couple of years, so I launched a chilled 31-day jam in December specifically with the goal of making games for blind gamers: https://itch.io/jam/games-for-blind-gamers
I recommend joining, why? You will definitely learn about game accessibility and blind gamers' needs, even if you don't end up shipping a game by the end. (It's a chill 31-day jam, so there's lots of time to explore and finish.)
