I liked the voice. It was believable. And it was obvious what was going to happen - when that's the case, the ending loses some of its impact. If the game was a little longer, if we got to know this patient more, that would probably evoke more emotion when you finish the game. Or adding a different ending - that would make it worth replaying.
There are a lot of spelling errors. Also, it's a bit too short. I get the idea and everything about why it's short, but there's not enough time to get interested in it.
