It is intended to be accessible to blind players, and I had some blind people test a similar game and they said it seemed ok. Specifically, there's a self voicing feature which reads out the dialogue and text on user interface things like buttons, and the game starts with the option to add extra image descriptions for things like character sprites, music, and backgrounds. I included a general guide to the controls in the main folder. If you press v it will activate self voicing.
That said, I haven't had any feedback from blind players on this specific game, so if you hit any issues or just have general suggestions please let me know! I'm disabled myself, though not in a way which affects my vision, so accessibility is very important to me, but I also know how easy it is for people to miss things. One obvious thing I'd have liked to do if I'd had the energy is add more descriptions of character expressions, but hopefully you can extrapolate most of them from the dialogue.
I really hope you are able to play and enjoy the game!
