+## Levels
+
+### Level 3: Healing Intro
+
+_You sense a larger sludge ahead, but you feel a bit weaker than usual._
+
+> **TIP:** You must heal between battles! Use `warrior.health()` to check your
+> health and `warrior.rest()` to regain health before fighting the second
+> sludge.
+
+#### Floor Map
+
+```
+╔══════╗

+╚══════╝
+
+@ = Warrior (10 HP)
+s = Sludge (12 HP)
+> = stairs
+```
+
+#### Abilities

+- `warrior.health()`: Returns your current health.

+- `warrior.attack()`: Attack a unit in front.
+
+_All subsequent levels are shifted up by one (old Level 3 → 4, etc.) to maintain
+progression._
