I just installed the screen reader NVDA to test this. First it sounded quite awkward until I realized that the voice-settings where set to German language which is not beneficial when reading English text! ;-)
But now I changed it to English and it perfectly works.
I find it exemplary that you enable people with visual disabilities to enjoy your game. Well done!
For people interested I can recommend Roguelike Radio episode 48 about "Designing for the Visually Impaired".
The game mechanics are also quite well-considered. I like how you combine a roguelike with a deck-building game.
