I don't play a ton of RTS games, so I really appreciate the tutorials, otherwise the main campaign would have totally kicked my butt 😅 - they were useful to get a feel of the game and try different areas out.
I tried it out with NVDA on, and my sense (as a sighted user) was that there was a lot going on and to keep up with , and I don't know that I would have been very successful had I not been looking at the screen (but that might be a biased take).
I agree with other comments that it was very chatty when on a structure, and saying just the updates may have been useful. Alternatively, having more distinct sound effects, and dedicated hotkeys to get the current health / units / threat / etc could have been useful.
Overall, there was definitely a lot of great stuff here, and the game itself was really enjoyable. Admittedly I'm always worried about building real-time experiences (instead of turn based ones), but seeing this honestly makes me inspired to try my hand at it, and see what else could be done in this space.
