Excellent little game. Very much enjoyed concept of using text as platformer. No explanation required other than the gameplay itself--a difficult achievement for any designer.
I can't agree with the wholly nihilistic ending. I thought a final redemption would have felt more rewarding and more useful as an emotion.
In terms of mechanics, I think it would be improved if there was some sort of marker that indicated which edges were legal exits to the next level--sometimes falling moved you forward, sometimes only the right wall, and sometimes either one. This is pretty confusing in a way that doesn't aid the theme.
Excellent game overall.
