Cool concept! I've played Before your eyes as well, it's cool to see another take on that idea. Really great job for your first gamejam! the blog post was a cool read as well. Sadly I didn't have a webcam, but to simulate the experience my partner was watching my eyes and pressing B when i blinked hehe.
I could see taking it in a slightly horrory direction being very interesting, since then then you can really play with what gets seen, missed and when a blink might get you in trouble, etc.
Great job overall!
