I like the concept, but.... I really don't know what I could make that would be "autism friendly" besides just another game. I just don't want to take a random game idea and make it for this because I feel like there should be a more specific drive behind a game made for this.
The only thing I can think of is trying to make a game that explains autism, but that seems too preachy to me and I know I wouldn't do a good job of it because of my low experience.
