Very unusual and even unsettling. It's a novel idea, taking a protagonist who is practically blind, removing the visuals, and using that to your advantage to ramp up the horror due to not knowing what exactly is going on. Thing is, I feel like the "not knowing" part is doing this VN a bit of a disservice. I sure would have liked a bit more explanation on the nature of the apparent apocalypse they've found themselves in, and I found most of the dialogue and character names difficult to follow. The good news is, that didn't take away from the eerie atmosphere, so this VN really sets itself apart based on that.
