Poor Misha.
Losing your eyesight is really scary, and usually in games we don't get as much tactile/sound information as we do in real life, but here it's quite different, I've never played something like this.
Nice job with the voice and sound, I can imagine how hard it was to test the game.
I had a small problem: I wanted to pause the game and accidentally closed it with escape
Other than that, very good and original!
P.S. How can I score a graphic if there isn't one?)
