This is one of the best ideas I've seen for this jam, though the execution could use a bit more polish.
Right now it's much too easy to game the system and create a dominant strategy. What I did was simply have everyone go to the middle and shoot in the exact same direction each time, creating a snake of bullets that was pretty easy to avoid.
If you keep working on it though, I'm sure you can find ways to prevent the player from doing that. Maybe adding a few walls, or perhaps the targets you have to shoot could be something other than your clones.
Other than that though, really great entry.
