How do you make a game for blind people? I’ve never done such or gave it much thought.

A wonderful question! We are super active on the discord so do stop by if you want faster feedback and even, but I'm glad I saw your question! 

The simple answer is audio. Screen reader for text, position audio, then specific sounds for actions.

Through that, TONS of games can be made accessible. Here's a list we made on our wiki of accessible games you can learn from. You might be suprised on what games are blind accessible! https://gamesforblindgamers.miraheze.org/wiki/Category:Example_Games

To add on to Ericbomb’s resources - make sure you check out Audiogames.net, which is a resource of many indie audio games, many of which were developed by blind people. One of my favorite blind developers to recommend is VGStorm who made the very popular Manamon and other similar games. Check his work out for inspiration.

Once you familiarize yourself with some of the game design used in audio games, try experimenting with how you can combine that with a sighted design. Remember that visually impaired people benefit from graphics!

I also recommend joining the Discord server. There are plenty of blind people there who can give you tips and tricks.
