last two lines don't really work for me here, not enough direction as to where this is supposed to be ending. if this is literal war and the next to last line is representative of the first shot/death, then the last ending exclamation mark reads a feel of fun and games/excitement into it which isn't supported by the rest of the piece. gives me a slap in the face type effect but i'm not entirely sure if it's in the direction you were intending. punctuation that fits a grimmer tone might work a little better, esp since you don't utilize much in the way of punctuation in earlier stanzas. (which really makes that exclamation mark stand out in odd ways.)

if it's a relationship metaphor, that's probably an on target reaction, in which case it might be nice to drop a few more clues farther up.
