I've been in the Scratch community for a while and haven't found many games blind people can play. Daniel Kish who can ride a bike by clicking his tongue to hear the echos of obstacles, inspired me to create this game. Anybody who can hear can play this. @MatteoCosmos and I made games of this type at roughly the same time without knowing about it. Here is a link to his game Invisible Walk. https://scratch.mit.edu/projects/188149848/
