I would LOVE more easily embedded accessibility features. Off the top of my head:
- colorblind visualizations - you could show how different palettes could look different to different people and then design accordingly.
- to translate these games to blind games, you could have the ability to add sounds for walls, items and have text to speech.
- for dyslexia you can opt for the open-dyslexic font instead of the classic low bit fonts (I know, I love the standard font too but it'll be good to have the option!)
I love the work you're doing!
