This was really cool, especially for a Ludum Dare game, but DANG it was hard as nails. There's so little room for error. I think it might have been better if enemies dropped letters only one at a time -- there were a lot of times when enemies just dropped all their letters into one column, which is way more dangerous than spreading them out. I overall felt like my human reaction times and mouse speed just weren't up to the task. Maybe if there was a text-to-speech protocol that let you call out words? Not sure what kind of software you'd need for that, though.
One thing I really liked is that you provided actual temptation for the violent option. I started off trying to be nice, but I was quickly forced to pick conflict because it's so much easier. A lot of morality games make the good and bad options equally effective or difficult, which completely defeats the point, in my opinion. It should be hard to be good in the face of conflict, and easy to give into temptation.
