I don't agree with the message, but I love how nicely you have delivered it. The method of deliverance has a "Jonathan Blow" feel to it, in a sense that it's not straight forward, but still not too confusing or pointless, it's just right enough to push the player into the process of interpreting this movements. The game-play is not bad either, but it gets really boring after a while, especially once you get that the levels are repeating with nothing changing. An idea that I have is that since you are shooting letters, maybe you can write something with the letters you have shoot down, and by writing the correct word win something...
