+Don't forget to make sure that all of the systems are now in `run_systems` (in `main.rs`):
+
+```rust
+impl State {
+    fn run_systems(&mut self) {
+        let mut vis = VisibilitySystem{};
+        vis.run_now(&self.ecs);
+        let mut mob = MonsterAI{};
+        mob.run_now(&self.ecs);
+        let mut mapindex = MapIndexingSystem{};
+        mapindex.run_now(&self.ecs);
+        let mut melee = MeleeCombatSystem{};
+        melee.run_now(&self.ecs);
+        let mut damage = DamageSystem{};
+        damage.run_now(&self.ecs);
+        self.ecs.maintain();
+    }
+}

 If you `cargo run` the project, it now behaves as you'd expect: the player moves, and things he/she kills die before they can respond.
