I feel bad...
My room mate is a much bigger Harry Potter fan than I am. She wants to play actively so bad but... she has MS and has extreme difficulty getting around. She got into Ingress with me but it wasn't very disabled friendly so she stopped and actually formed a hatred of Niantic due to their response to her. When she requested more disability access to play, she was told (I was there - it was at a Detroit anomaly) "This game is for people who can walk. The point is to get out and exercise." She spent the rest of the anomaly in the hotel room.
She actually was very hesitant to download this game and start playing but she did due to her love of HP. However, the limitations are still an issue and she can't play except for at home or if I drive her around (which I don't mind). But so much of it requires personal activity (many POIs are not accessible by road/parking) that she just can't do it effectively.
So why do I feel bad? Because I really want her to enjoy this game. She's so into Harry Potter that I want this to be an incredible experience for her. I don't know what the answer is or how to make it better for people with disabilities, but I would ask Niantic to seriously consider this. She can't be the only one who really wants to play your games.
Please consider. Please think about it. Please make it more disabled friendly.
