Good concept, but needs polish.
To the last reviewer: You're an idiot. This isn't meant to be educational. Rhete was just trying to make an inventive set-up.
And inventive it is. I actually like this idea a lot. It reminds me greatly of the game "Typing of the Dead." However, the game itself is quite boring. You move at a very slow pace, and instead of typing out single letters, it would be great if you had to type out actual words or phrases, which would up the difficulty a lot. Not only that, but the space bar manuevering is very gimmicky and unintuitive. Still, this is a great concept to build on.
