Congrats on getting a submission for the jam.
I think there are some basic flow things that probably need better screen reader support (some of the modals didn't have the best affordances on what was being shown or how to close them). I think there's a lot of bits here that are nice, but probably don't add a ton of value for blind players (like setting the unit colors), and I wonder how much of the modals and configuration you could cut out to make it easier to get straight into the game!
Side note - I'm surprised you didn't end up making a web build since this uses Web Awesome - I'm genuinely curious how you put this together (since I've been following the Web Awesome development for quite a while, and I'm working on my own web applications with it as well).
Again, congrats on making the submission and thank you for sharing it for the jam!
