Needs some technical work
At the point where you're getting pinned down I noticed that there was some serious trouble in parsing what I was typing... what would happen was something like this:
1) I type a word to shoot at someone in the back
2) It takes so long for the arrow to get back there that I type four or five other words before it hits
3) The word I've already typed is displayed there, so I start typing it again
4) Something in the middle of the word overlaps with the beginning of a new word on the screen
5) I now am jammed, because I have part of some random word on screen and I can't tell what's going on.
You need to have the word boxes disappear the second that you can't type the word anymore, rather than waiting for the arrow to get to the monster, since the arrows fly so slowly.
