I had to dock you some points on Presentation because that screen shake was too much. Also, a visual cue for Keycap Pullers carrying a key would have been helpful. Make them glow or something to show they are a priority target.
The idea of using the whole screen as a lifebar was really good, though. So the presentation is a mixed bag. Great idea, nice job! And the "How will you type?" message made me chuckle.
