Yes, the command line version is currently blind accessible because it is screen reader compatible (I use NVDA to test, but others have reported that Narrator and JAWS also work)! I’m working on adding text-to-speech to the graphical version, but it’s not done yet (as of version 0.0.15).
Here’s an AudioGames forum thread for more history and context about Upheaval’s blind accessibility. 🙂
